Hi Jeepee,

Is UE4 crashing when trying to open a project you’ve been working on or has the editor never opened at all? There are different ways to troubleshoot either condition so please provide this information and we will continue to investigate.

Thanks,

Hi Jeepee97,

There are number of errors with blueprints in your log just before the critical error that need to be addressed:

Can’t package game: “…has an inappropriate outermost”

If you cannot open your project, try opening the DefaultEngine.ini in a text editing program and changing the default map to “None.” This should allow you to open to a blank map at which point you can fix the blueprint errors, then open your main level map.
