If looks like your GPU can’t hack it. What model is it?

Try booting in DX11 instead of DX12.

I haven’t done stuff with RHI in a while but I guess you can set the value in an ini file if you can’t get into the editor. It could be:

YourProject\Saved\Config\WindowsEditor\Engine.ini

[/Script/WindowsTargetPlatform.WindowsTargetSettings]
DefaultGraphicsRHI=DefaultGraphicsRHI_DX11

Should be it, I scanned for code using this value in one of my plugins. Expected values should be

/* DefaultGraphicsRHI_DX11 - DefaultGraphicsRHI_DX12 - DefaultGraphicsRHI_Vulkan */

I could not find the file you described… but thanks for your help! It seems that my PC is too old to use UE5.

It seems that UE5 could not be used due to insufficient performance of the GPU (intel uhd graphics 630).
I installed UE4 and it worked. Thank you for your answer!
