Strange artifacts appear on some of my assets

Hello,
I’m asking you for help because I have a very annoying problem with the unreal engine 5.
regularly, after 15 to 30 minutes of work, strange artifacts appear on the assets. This is accompanied by major performance problems. (See screenshots)
So I have to restart my engine regularly to solve the problem.

I recently changed my graphics card thinking that was the problem, but it did not solve the problem…

Would you have a solution to the problem please? :slight_smile:

I specify that I have the following configuration:
i9 9900k (Stock)
32 Go Ram 3000MHz
RTX 3080 FE (Stock)
Both the project and the engine are stored on an NVME

I have the exact same problem - I simply cannot use Unreal 5 until this has been sorted out. I either have to go back to using 4 or stick to Blender.
