LogD3D12RHI: Error: Failed to create pipeline state with combined hash.- Crash in editor and packaged builds (Source Build of Engine)

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.
