Try the solution posted here: How to fix Unreal 5 Boot issue?

I tried, but in my case that generates another type of crash:
Assertion failed: ComputePipelineState [File:D:\build++UE5\Sync\Engine\Source\Runtime\D3D12RHI\Private\D3D12StateCache.cpp] [Line: 1208]

That said maybe it works for you

Have you tried all the solutions given in the other topic? There’s about 3 or 4 different possible ones - one of which is to do with Windows 11. I could only mark one as the actual solution which was the one that worked for me, but others have tried different methods.

I’ve read that there is an UE issue with Windows 11 that relates to DirectX12 and that maybe reverting to DX11 could solve this issue.

However as I don’t use Windows 11 I cannot comment further on the issue. I stopped looking into it once my solution worked so I don’t know the underline cause.
