Hey there @UnderClever! It’s acting as though your current platform is invalid for the selected RHI. Open the project files → Config → DefaultEngine.ini
[/Script/WindowsTargetPlatform.WindowsTargetSettings]
DefaultGraphicsRHI=DefaultGraphicsRHI_DX12
-D3D12TargetedShaderFormats=PCD3D_SM5
+D3D12TargetedShaderFormats=PCD3D_SM5
+D3D12TargetedShaderFormats=PCD3D_SM6
-D3D11TargetedShaderFormats=PCD3D_SM5
+D3D11TargetedShaderFormats=PCD3D_SM5
Change the default graphics down to DX11
DefaultGraphicsRHI=DefaultGraphicsRHI_DX11
and see if the project launches. If so, then we’ll dig through your shader model as well to see.
What are your computer’s specs?
