Hey again Stagehand.
The most common reason behind exception_access_violation error is a program trying to access a particular memory location without read/write permission. Corrupted system files, such as system DLLs or registry entries, can also prevent applications from functioning properly and show you this error message.
So the first thing you need to do is make sure Unreal is running as administrator. If it still crashes with this error, I hate to break it to you… It’s probably your windows installation
