I’m adding to the chorus here. Not sure when this started but even a fresh first person project in 5.4.4 crashes without even opening, unless I delete or change the defaultengine.ini.

If I delete these lines, I don’t get the crash:  
`-D3D12TargetedShaderFormats=PCD3D_SM5`  
`+D3D12TargetedShaderFormats=PCD3D_SM6`

Or if I change  
`DefaultGraphicsRHI=DefaultGraphicsRHI_DX12`  
to  
`DefaultGraphicsRHI=DefaultGraphicsRHI_DX11`  
Then that also works for me.

But this seems like a temporary workaround. Rolling back my Nvidia drivers also didn’t help. But now that I see people had this problem back in July I can see that it seems like not a driver issue.
