Using an automated script in command line arguments to build project map causes a crash.
Note: that it will not crash when 'UseSCC=false' is omitted, but it will not build the map either. Screen grab of call stack Debug has been attached.
UE4Editor.exe "C:\MyTestProject\MyTestProject.uproject" ThirdPersonExampleMap.umap -AutomatedMapBuild UseSCC=false
Result: Unreal Editor crash. Logs have been attached.
Expected: Map successfully loads.
Regression: Yes
