Are you using a binary version of the engine (From the epic launcher)?
If so try verify engine files.
Go into your DefaultEngine.ini and set these values to none.
This will load no map by default which may help if your map is broken.
[/Script/EngineSettings.GameMapsSettings]
EditorStartupMap=None
GameDefaultMap=None
Also looks like the issue has somthing to do with VR if you made any VR releated settings just revert them.
