This is a major bug we are all having epic, Please Help us get this fixed asap. Its holding a lot of map publications and changes back!!!

I managed to solve this problem by deleting actors until the map loaded correctly, after that load a backup with all the actors as they were, that is, a version without deleting anything, and since the project size already loaded thanks to that ā€œlighterā€ version, it will now always load, the only negative thing is that every time the project size is reset, either by a game update or island restart, the error could appear again and I would have to repeat the same step over and over again until Epic Games completely fixes it :c

Hey folks, weā€™re going to need UEFN logs to investigate. Could you either post them here or DM them to me?
