My current investigation results:
- UE crashes when I try to open problem level; Standalone crashes at start.
- From crash report: MaterialParameterCollection.h. I have three meterial parameter collections in my project. I just tried to remove them. Materials was broken, but I was able to open level and even test standalone.
- I found problem collection, tried to remove only it - all works fine.
- I don’t remove it - just open, close without saving and then check - world is opened without crash, but standalone still crashes. Tested many times.
Will continue investigation, maybe will hardcode collection into all materials.
