Launching session doesn't work anymore

Hey, since the latest version was updated I am not able to “Launch Session” anymore from one of my maps.

Basically I click “Launch Session” and it loads fortnite, then loads the splash screen " Loading into your Edit Session" then it just disconnects. The screen will be the same but the session says disconnected within UEFN. Also sometimes it will go into the preloading lobby but then gets disconnected from there.

My other maps load fine, just this one has been affected. Not sure if you guys have encountered this or not.

Thank you for your report! We would like to look into this further, would you be able to submit a bug report using the form available here: Fortnite Creative
