thing that worked for me on ue 5.1 with dx11 was using cmd to run ue by this command

\your\path\to\UE_5.1\Engine\Binaries\Win64 > start UnrealEditor.exe -dx11

You have a nvidia driver issue with using directx12 (which UE5 does by default). Try running UE5 Editor with appended -dx11 on the comandline to see if you get rid of this error or extend -log to see all the startup in a new logfile for debugging (or use LOG=filename.log to log into separate file). With my NVidia GTX Series I can't use any dx12 rendering in UE5 and UE4. So I guess cleaning nvidia driver settings and reinstalling should fix it. You can define in your UE project settings to use DX11 (after starting with -dx11 or changing the default rhi in the ini file) but this will disable features like RayTracing.
