Train simulator world crashes on startup

I recently installed TSW and on startup the splash screen displays for a few seconds and then the process crashes with the following message, An Unreal process has crashed: UE4-TS2Prototype

This might not be the right place for this question. You can better ask the question at Dovetail games ( since they created the game.

The answerhub at unreal engine is for Unreal Development questions not for game questions.
