Hey there, I have a level inside my project that I haven’t been working on for a few months. Trying to open it again and it crashes out every time. The project is in UE 4.26 and everything else in the project seems to be working fine.
Hopefully someone can help me solve this problem, ill copy and paste the crash report below for anyone who might be able to help.
I’d greatly appreciate any help trying to solve this!
