Description

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. 

Steps to Reproduce
  1. Open Unreal Engine 4.23 Preview 4.
  2. Create a new C++ Third Person Template Project.
  3. In the Command Line, CD into your Engine 4.23 preview installation path, and enter the following(substituting path and project name as necessary) :
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
