Unreal Engine 5.(3.4.5) keeps crashing, no solution from the forum helps

Hello,

Unreal Engine 5 keeps crashing on my device (Lenovo Legion 7 16IRX8H), but the same project runs stably on other computers. I have tried all the solutions I found on the forum, but nothing has worked.

I have submitted error reports through the built-in system, but the issue persists. Who can I contact to investigate the cause and find a solution?

Thank you in advance for your help!

From the report, it seems to be a GPU crash issue, specifically triggering the crash in the UnrealEditor_D3D12RHI module.

For this error, I suggest you update the graphics driver on your device, or try switching the graphics API (such as switching from D3D12 to DX11 or Vulkan)

The driver is updated, switching gives the same error only with dx11

If it still doesn’t work, you can try the following solutions:

  1. If it is a project-level error (crash when opening a project), try to recreate a blank project, cancel ray tracing, or minimize the Unreal Engine configuration to see if it can be solved.

  2. If it is an engine-level error (occurs when opening Unreal Engine), then the situation is more complicated. You can try to reinstall Unreal Engine to solve the problem, or run command

sfc /scannow

on the device to repair damaged files. If all fail, it may be that the configuration itself is incompatible with the UnrealEditor_D3D12RHI module.

The error appears when I add a camera and a sequencer. And with its help I animate objects. Even a cube in an empty project.
