How Do You Fix UE-Marvel Unreal Process Crash with Unhandled EXCEPTION_ACCESS_VIOLATION Error?

The “Unhandled Exception: EXCEPTION_ACCESS_VIOLATION” error is a common issue that occurs when a game or program tries to access restricted memory, causing it to crash. This problem often arises in new games due to bugs, outdated drivers, or poor optimization. Below is a detailed guide to fix this error effectively.

Quick Fixes to Try First

1. Free Up Disk Space: Ensure at least 10GB of free space on your OS drive (usually C:). This allows Windows to manage system processes and temporary files properly.
2. Update Graphics Drivers: Outdated drivers can cause compatibility issues with newer games. Always keep them up to date.
3. Adjust Graphics Settings: Set your game’s graphics settings to medium or higher. Strangely, lower settings can sometimes cause rendering issues due to poor optimization.
4. Run as Administrator: Right-click your game launcher (Steam/Epic) and select Run as Administrator to resolve permission-related issues.
5. Re-login Your Account: Log out and back into your game account. This simple step can fix login-related problems.
6. Disable Overlays: Turn off overlays from programs like Discord, Steam, or Nvidia GeForce Experience, as they can interfere with the game.
7. Correct Date and Time Settings: Ensure your PC’s date and time are accurate. Mismatched settings can disrupt server synchronization for online games.

Solution 1: Verify and Repair Game Files

Corrupted or missing files are a frequent cause of crashes. Follow these steps:

1. Open your game launcher (e.g., Steam or Epic Games Launcher).
2. Navigate to your game library and locate Marvel Rivals.
3. Right-click the game and select Properties (or equivalent).
4. Go to the Local Files tab and click Verify Integrity of Game Files.
5. Wait for the process to complete, then relaunch the game.

Solution 2: Delete Crash Dump Files

Crash dump files accumulate over time and may cause repeated crashes:

1. Open File Explorer and go to: C:\Users\\AppData\Local\Marvel\Saved\Crashes
2. Delete all files in this folder.
3. Empty your Recycle Bin and restart the game.

Solution 3: Clear RAM Cache with RAMMap (Optional)

If you experience occasional crashes due to limited RAM:

1. Download Microsoft’s RAMMap tool.
2. Run it as Administrator.
3. In the tool, go to Empty > Empty Standby List to clear cached memory.
4. Relaunch the game after clearing unnecessary data.

Solution 4: Use Compatibility Mode

Older systems may require compatibility adjustments:

1. Locate the game’s executable file (.exe).
2. Right-click it and select Properties > Compatibility tab.
3. Check Run this program in compatibility mode for: and choose Windows 8 from the dropdown.
4. Click Apply and test the game.

Solution 5: Reinstall the Game

If none of the above works:

1. Uninstall the game via your launcher (e.g., Steam).
2. Restart your PC.
3. Reinstall the game from your library for a clean setup.

Solution 6: Wait for Developer Patch

Sometimes, only a patch from the developers can resolve persistent bugs:

• Monitor forums, social media, or patch notes for updates.
• Report your issue on Marvel Rivals’ official support page to help expedite fixes.

By following these steps, you should be able to resolve most instances of the “Unhandled Exception” error effectively.
