I spoke with @pdoane and the workaround is to change these lines to false and it will run successfully.

I believe this issue is already known, but I just wanted to stick an issue up for tracking :) Thanks!

The DirectX Graphics Tools support feature needs to be enabled on Windows for this to work. https://learn.microsoft.com/en-us/windows/win32/direct3d12/directx-12-programming-environment-set-up

So I think this should be changed to not panic if enabling debug layer fails. Maybe issue a warning in debug mode.

It is also possible to have the debug layers enabled in release mode.
