Crash occurs when using the VisRT console command in a project launched without the Editor using D3D12

Launching a project outside of the Editor (-game) using D3D12 (-d3d12) results in a crash if the console command VisRT is used in the project.

PREREQUISITES:
This requires a D3D12-capable machine, so use of the Win10 OS is required.

1. Create a new Blueprint project.
2. Open a command prompt where your UE4Editor executable is located (Engine\Binaries\Win64).
3. Enter the following command at the command prompt: UE4Editor.exe "<Path to .uproject file created in step 1>" -game -d3d12
4. Confirm that the project launches without the Editor.
5. Press the ` key to open the console.
6. Enter the command VisRT.

RESULT:
A Windows error message appears stating that the video driver crashed and restarted, and a Crash Reporter window is displayed with the error: Assertion failed: SUCCEEDED(hr) [Link Removed] [Line: 283]

EXPECTED:
The Engine does not crash or cause the video driver to crash.

Assertion failed: SUCCEEDED(hr) [Link Removed] [Line: 283]
