Hmm I’m using Visual Assist with Visual Studio so it might be the reason I can find it. The path should be something like: C:\Program Files\Epic Games\UE_4.22\Engine\Source\Runtime\Core\Private\Modules\ModuleManager.cpp
Are you able to check the Unreal Editor logs (Or run it via Visual Studio and watch the debugging output)? If it crashing on that then the ensureMsgf should also be telling you the name of the module that it’s failing on.
