Session Crash When Ending the Game

Summary

I’m having an issue with one of my maps. I can launch the session without any problem, but as soon as I stop the game, Fortnite freezes and crashes. This only happens with this specific map.

I haven’t used anything unusual in the map compared to my usual workflow. I also tried reverting to older saves from when everything was working fine, but the issue still persists.

Could you please help me figure out what’s causing the crash?

Thank you in advance!
