Hey, did you figure out what was the problem?
I’m facing same problem but in my case it says “check the output logs for details”, but there’s nothing in the logs lol
It’s a project I worked on in the past, it worked just fine every time! Now it’s a nightmare! I just changed one map, didn’t change anything else but the map geometry.
Tried everything you said there, also changing to DirectX 11, none of this worked.
