How to Fix EXCEPTION_ACCESS_VIOLATION (0xC0000005) on Cyberpunk 2077

Cyberpunk 2077 players might encounter the EXCEPTION_ACCESS_VIOLATION (0xC0000005) error, an annoying interruption that crashes the game and sends you back to your Windows PC desktop without warning. This error typically stems from memory issues, where the game tries to access an area of memory that it’s not supposed to. Such a disruption not only halts your progress but can also lead to loss of unsaved game data, making it a significant concern for gamers.

The error code 0xC0000005 might sound like a random string of characters, but it’s actually a signal that there’s a specific problem with how Cyberpunk 2077 is running on your computer. It’s known as an EXCEPTION_ACCESS_VIOLATION, which in plain terms means the game is trying to reach out and touch a part of the computer’s memory that’s off-limits. This can cause the game to crash, often taking you back to your desktop without saving your progress.

In Cyberpunk 2077, this error tends to pop up at certain moments, like during a game save or when the action on screen gets particularly intense. It’s not picky; it can occur whether you’re roaming the neon streets of Night City or in the middle of a firefight. The error doesn’t mean your game or save is broken, but it does mean that something’s not communicating correctly inside your Windows computer.

Fix 1: Update Your Graphics Card Driver

Keeping your graphics card driver updated is crucial. It’s like ensuring your car’s engine is tuned up for a smooth ride; for your games, it means better performance and fewer crashes. Manufacturers frequently release updates to fix bugs and improve your gaming experience, so having the latest driver can often resolve issues like the EXCEPTION_ACCESS_VIOLATION error.

Here’s how to update your graphics card driver:

  • Open the “Device Manager” on your computer. You can do this by typing “Device Manager” into the search bar near the Start menu.
  • Expand the “Display adapters” section. You’ll see the name of your graphics card listed here.
  • Right-click on your graphics card and select “Update driver.”
  • Choose “Search automatically for updated driver software.” Your computer will then check for any available updates and guide you through the installation process.
  • If your computer doesn’t find anything, don’t stop there. Visit the website of your graphics card manufacturer (like NVIDIA, AMD, or Intel), go to their drivers section, and download the latest driver for your specific model.
  • After downloading, run the installer and follow the prompts to complete the update.

Remember to restart your computer after updating the drivers. Restarting ensures all changes take effect properly.

Fix 2: Reinstall Java Runtime Environment

Java isn’t just for websites and mobile apps; it’s also a key player behind the scenes for some games and applications, including elements of Cyberpunk 2077. If Java isn’t up to snuff, it could be the culprit behind some game errors. Reinstalling Java can refresh the files needed for smooth gameplay and might just iron out those error wrinkles.

To reinstall Java, follow these steps:

  • Head over to the official Java website to download the latest version of the Java Runtime Environment (JRE).
  • Before installing the new version, it’s wise to remove the old one to prevent any conflicts. Go to the Control Panel, find “Programs and Features,” and uninstall any Java versions you see.
  • Now, run the installer you downloaded from the Java website. It will guide you through the process, which is mostly just clicking ‘Next’ until it’s done.
  • Once the installation finishes, give your computer a fresh start with a reboot.

With a fresh install of Java, Cyberpunk 2077 should have what it needs to run more smoothly. If the error persists, it might be time to look into other potential fixes, but a fresh Java installation is a good step towards a solution.

Fix 3: Configure Data Execution Prevention (DEP) Settings

Data Execution Prevention, or DEP, is a security feature that can help prevent damage from viruses and other security threats. However, sometimes it can be a little overzealous and block legitimate programs like Cyberpunk 2077 from running properly. If DEP is stopping your game from running smoothly, tweaking its settings might just do the trick.

To adjust DEP settings and add Cyberpunk 2077 to the exceptions list, here’s what you need to do:

  • First, you’ll need to open the System Properties on your computer. You can do this by right-clicking ‘This PC’ or ‘Computer’ on your desktop and selecting ‘Properties,’ then clicking on ‘Advanced system settings.’
  • Under the ‘Performance’ section, click on ‘Settings,’ and then go to the ‘Data Execution Prevention’ tab.
  • You’ll see two options here. Choose the one that allows you to select programs you do not want DEP to check.
  • Click on ‘Add’ to navigate to the executable file for Cyberpunk 2077, which is usually located in the folder where you installed the game, and select it.
  • Apply the changes and restart your computer for them to take effect.

By setting DEP to ignore Cyberpunk 2077, you’re essentially telling your security system to trust the game, which should help eliminate the error if DEP was the cause. Remember, DEP is there to protect your system, so only add programs you trust.

Fix 4: Adjust User Account Control Settings

User Account Control, commonly known as UAC, is a security module in Windows. Its job is to prevent unauthorized changes to your system. But sometimes, it can interfere with the smooth running of games like Cyberpunk 2077, mistaking them for potential threats.

Disabling UAC might help if you’re running into the EXCEPTION_ACCESS_VIOLATION error. Here’s how you can adjust the UAC settings:

  • Search for ‘UAC’ in the start menu and select ‘Change User Account Control settings.’
  • In the window that opens, you’ll see a slider to set the level of UAC ranging from ‘Always notify’ to ‘Never notify.’
  • Slide down to ‘Never notify’ to turn UAC off. This action will require administrative privileges.
  • Once you’ve made the change, hit ‘OK’ and restart your computer to apply the new setting.

Turning off UAC can make your system more vulnerable to threats, so it’s a good idea to re-enable it once you’re done playing the game. This is a temporary fix and should be used with caution.

Fix 5: Verify Game Files and Patches

Game file integrity is essential for Cyberpunk 2077 to run without hitches. Corrupted or missing files are often the root of many errors, including the dreaded EXCEPTION_ACCESS_VIOLATION. Ensuring all game files are in order and patches like 2.02 are correctly applied can often resolve these issues.

To verify the integrity of Cyberpunk 2077 files, follow these steps if you’re using a platform like Steam:

  • Open your Steam client and navigate to the library section.
  • Right-click on Cyberpunk 2077 in the list of games and select ‘Properties.’
  • Go to the ‘Local Files’ tab and click on ‘Verify integrity of game files.’ Steam will then check your game’s files and replace any that are incorrect or missing.

If you’re using a different gaming platform, look for a similar option to verify game files in the application’s settings or help section. This process ensures that all the necessary files are exactly as they should be, which is crucial for a complex game like Cyberpunk 2077. After the verification process, the game will download any missing or corrupted files, ensuring that the latest patches are properly integrated.

Fix 6: Close Conflicting Background Applications

Sometimes, the software running in the background of your system can clash with Cyberpunk 2077. These conflicts can cause errors as both the game and the other applications vie for the same system resources or cause interference in processes.

To identify and close these background applications, you can use the Task Manager:

  • Press Ctrl + Shift + Esc to open the Task Manager.
  • Look through the ‘Processes’ tab for any applications that are not essential for running your system or the game.
  • Select any non-essential applications and click ‘End Task’ to close them.

Be cautious with what you choose to shut down; ending critical system processes can cause instability. Stick to closing programs you recognize, like web browsers or music streaming services, that aren’t necessary for your gaming session. This can free up resources and potentially stop the error from occurring.

Fix 7: Reinstall Cyberpunk 2077

There are times when the only solution left is to start fresh. Reinstalling Cyberpunk 2077 can resolve persistent issues that other fixes can’t touch, especially if the problem lies deep within the game’s files. If you’ve tried every other method and the error persists, reinstalling Cyberpunk 2077 could be the answer. This step ensures that any deep-seated file corruption or complex issues are completely removed.

Start by uninstalling Cyberpunk 2077, which you can do through the control panel or directly within the game platform, like Steam or GOG. After the game is uninstalled, a system restart is a good practice to clear out any temporary files and ensure no related processes linger in the background.

Once your system is up and running again, proceed to reinstall the game. Make sure to download the latest version, which may include updates or patches that could prevent the error from reoccurring. It’s also wise to keep a backup of your game saves, although many gaming platforms handle this automatically. A fresh installation can often clear up the issues that were causing the error, giving you a clean and updated version of the game to enjoy.


Cyberpunk 2077 offers an immersive and thrilling gaming experience that’s hard to match with its rich storytelling and expansive open world. These fixes are designed to smooth out any disruptions, ensuring that players can dive back into the vibrant and gritty streets of Night City. With these solutions in hand, players should be able to tackle any technical issues and return to enjoying the game’s deep narrative and action-packed gameplay.
