Crash when debugging project offscreen

Running a project with the RenderOffscreen flag in the DebugGame configuration applied causes the debugger to crash.

Tested in 4.21.2 (CL - 4753647), 4.22.1 (CL - 6063286), 4.23 (CL - 6674923)

1. Enable [UnrealVS|https://docs.unrealengine.com/en-US/Programming/Development/VisualStudioSetup/UnrealVS/index.html] for Visual Studio
2. Download the attached [Link Removed]
3. In the Visual Studio Solution run the project in DebugGame, with the "-game -RenderOffscreen" flags applied

Expected: The project runs the executable and exits on play

Result: The executable crashes on load
