    Description

      When using the D3D12 rhi backend if you attempt to import an existing ID3D12Device it will crash. I've got a patch that fixes this already which I will attach in a sec, the problem is that the activeAdapter is not set for the code path where you import an existing device which then causes logic to call IDXGIAdapter1::GetDesc on an uninitalized pointer.

      Attached is a simple project which demonstrates the issue.
