Part 1: Understanding the Error - What Is EXCEPTION_ACCESS_VIOLATION?
Before diving into the fixes, it’s important to understand what this error means. An "EXCEPTION_ACCESS_VIOLATION" occurs when Unreal Engine 5 (or any software) attempts to access protected memory or perform operations that the system deems unsafe. Essentially, it's a memory violation error where the engine is trying to read or write to a location in memory that it’s not allowed to.
The error message often contains a memory address like "0x00007fff1d087718," which can vary from user to user. While these addresses are specific to each case, the root causes of the error tend to be similar, which makes it easier to troubleshoot.
Common Causes of the EXCEPTION_ACCESS_VIOLATION Error in Unreal Engine 5:
Corrupted game files or project files
Incompatible hardware or outdated drivers
Memory management issues (e.g., RAM problems)
Misconfigured Unreal Engine settings
Third-party plugins or software conflicts
Insufficient system resources for large projects
Faulty or missing system libraries
In most cases, these errors can be fixed by adjusting a few settings or updating your system. Let’s get into the practical solutions.
Part 2: Quick Fixes for EXCEPTION_ACCESS_VIOLATION
If you’re in the middle of a project and need a fast fix, start with these basic steps:
1. Verify Your Project Files
Corrupted or missing files in your project could cause Unreal Engine 5 to crash. Luckily, this is easy to fix:
Go to the Epic Games Launcher
Select Library and locate your UE5 project.
Click on the three dots next to the project and select Verify.
This process will check all your project files for corruption and replace any that are broken or missing. Once the verification is complete, try running Unreal Engine again.
2. Update Your Graphics Drivers
Outdated or corrupt graphics drivers are one of the most common causes of the EXCEPTION_ACCESS_VIOLATION error. To ensure this isn't the problem, make sure your GPU drivers are up to date:
NVIDIA Users: Visit the NVIDIA Drivers page and download the latest drivers for your graphics card.
AMD Users: Go to the AMD Drivers page and update to the latest version.
After updating, restart your computer and try running Unreal Engine 5 again.
3. Disable Third-Party Plugins
Third-party plugins can sometimes conflict with Unreal Engine, especially if they're not optimized for UE5. To rule out plugin conflicts, try disabling all non-essential plugins:
Open your project in Unreal Engine 5.
Go to the Edit menu and select Plugins.
Disable any unnecessary third-party plugins and restart Unreal Engine.
If the error goes away after this, you can re-enable plugins one by one to identify the culprit.
Part 3: Advanced Fixes for EXCEPTION_ACCESS_VIOLATION
If the quick fixes didn’t work, it’s time to dive into more advanced solutions.
1. Adjust Virtual Memory (Paging File Size)
Sometimes, Unreal Engine can run into memory issues if your system’s virtual memory is too low. To manually adjust the size:
Right-click on the Start button and select System.
Click on Advanced System Settings on the left.
In the Performance section, click on Settings, then navigate to the Advanced tab.
Under Virtual Memory, click Change.
Uncheck Automatically manage paging file size for all drives.
Select your system drive and click on Custom size. Set the Initial size and Maximum size to a value that is about 1.5 to 2 times your physical RAM size (e.g., if you have 16GB of RAM, set it to 24,000MB to 32,000MB).
Click Set, then OK.
Restart your system and try launching Unreal Engine again.
2. Reinstall Unreal Engine 5
If none of the above steps work, you may need to reinstall Unreal Engine to rule out installation issues:
Open the Epic Games Launcher.
Navigate to Library, locate Unreal Engine 5, and click the three dots next to it.
Select Uninstall.
After uninstalling, restart your system and reinstall Unreal Engine 5.
This fresh installation can resolve issues caused by corrupted engine files.
