This error message suggests that there is a problem with the graphics driver or the GPU. The error “EXCEPTION_ACCESS_VIOLATION reading address 0x000001c65bc205d0” usually indicates that Unreal Engine is trying to access memory that it is not allowed to access. It could be caused by a problem with the GPU driver or the GPU itself.
Try these steps to fix this issue:
- Make sure that you have the latest GPU drivers installed for your graphics card. You can download the latest drivers from the website of the GPU manufacturer (NVIDIA, AMD, etc.).
- Try disabling any third-party software that may be interfering with the GPU, such as overclocking software or other system monitoring tools.
- Disable any custom graphics settings in your game or in the Unreal Engine editor, such as custom resolution or anti-aliasing settings.
- Check for any other software that may be conflicting with Unreal Engine, such as other game engines or graphics-intensive software.
- Try running the game or the editor on a different machine to see if the problem is specific to your current setup.
It’s also worth noting that this error could be caused by a hardware problem with the GPU, such as overheating or a malfunctioning component. In this case, it may be necessary to replace the GPU.
