Its happening to me too, after I started to run my project in the UE5 I can’t Build All Levels anymore. Any clues or fixes?
Edit1: I’ve found that even hiding all Levels and skipping them on Build All Levels gives the same crash.
Edit2: I’ve rolled back to a commit before any changes made after UE5 and the crash still happens, so either the problem is in the UE5 or with my projectS that were made in UE4.26 .
