Please include crash logs and dump files for your project after it crashes.
I’d like you to try opening project without a default map. Please go to your project folder > Config and open DefaultEngine.ini file there. You should this line:
EditorStartupMap=/Game/Maps/Example_Map
Delete /Game/Maps/Example_Map part, save file, and try to open project again.
Great! Let us know if you run into other problems with that map. At least now we’ve narrowed cause of problem down if it happens again. Good luck with your project!
