I noticed on AnswerHub a lot of people are suffering from UEEditor has crashed or UEEdtior.cmd has crashed. Yesterday, I too had that problem. I tried all the fixes on the AnswerHub, but like many the solutions didn’t work. I reinstalled Unreal a few times from Binary and Source, no luck.
Nvdia driver issues? Nope.
None of all of the fixes would work, I spent the whole day trying to fix it. I reinstalled Visual Studios, still nothing. Then…
I DELETED THE MAP THAT UNREAL ENGINE WOULD LOAD UP IN MY PROJECT WHEN IT OPENS.
For me, this was “Hubworld”. I have 5 maps, so I deleted the Hubworld map (Which I had swapped out for a back-up earlier and it still didn’t work).
However, getting rid of the map completely… WORKED.
This is just another solution to the problem, but it worked for me. Maybe it’s a hint as to why this is happening. I’ll upload the map file so the beautiful people at Epic can take a look to see if there’s something in the file that’s causing the issue to happen.
