This is not a regression. Tested in //UE5/Release-5.0 CL20379098
Editor crashes with an assertion after executing the command r.RHIThread.Enable 2
Expected Results:
A warning to prevent the command since 1 or 0 is expected, or RHIThread would start running on that dedicated thread.
Actual Results:
The editor crashes with an assertion:
Assertion failed: GRHICommandList.OutstandingCmdListCount.GetValue() == 1 [File:D:\build\++UE5\Sync\Engine\Source\Runtime\RHI\Public\RHICommandList.h] [Line: 5221] Expected only 1 outstanding RHI command list. Outstanding: 2
