AllowCommandletRendering D3D12 device crash

(Optional) Clean + build of UE4 Development Editor Win64

In ShooterGame DefaultEngine.ini, set:

[/Script/WindowsTargetPlatform.WindowsTargetSettings]
DefaultGraphicsRHI=DefaultGraphicsRHI_DX12

[/Script/Engine.RendererSettings]
r.RayTracing=True

Run UE4Editor-Cmd.exe [Link Removed] -run=Cook -TargetPlatform=WindowsNoEditor -fileopenlog -unversioned -iterate -iterateshash -AllowCommandletRendering -stdout -CrashForUAT -unattended -NoLogTimes

Loads fine. Open ShooterGame in same UE4 build + wait for ShooterGame shaders to complete compile. Close UE4.

Re-run UE4Editor-Cmd.exe [Link Removed] -run=Cook -TargetPlatform=WindowsNoEditor -fileopenlog -unversioned -iterate -iterateshash -AllowCommandletRendering -stdout -CrashForUAT -unattended -NoLogTimes

Should crash. 2 different errors 1. See callstack, 2. "LogD3D12RHI: Error: Failed to choose a D3D12 Adapter."
