Summary

Before a few days something happened with my map and now everytime when I click on Launch Session in UEFN it starts the game like before, like normal but after a little the game just crashes and don’t want to load my map so I can play test the new changes I make! Idk why, please help!

Steps to Reproduce

Before I few days I had turn off all my 2FA options so I can freely loginf into one Xbox Account for something, the account was with different name that what it’s mine on the PC! But then I unlincked it and turn on all my 2FA back again. That where I started having this problem (after I turned off my 2FA). I also verifyed the UEFN and Fortnite files trough the Epic Games Store and tryed deliting the part of the island I was working on and everyting placed on it, to see if that will help somehow, but it didn’t, so I return everything back from the Undo History. So maybe something from this things that I did is causing the issue, idk.

Expected Result

I expect my issue to be resolved soon so I can get back to smoothly finishing my map which I was planning to release sometime these days.

Observed Result

Maybe here you asking for the Observed Result after I click Launch Session in the UEFN. So here is everything that I think it will be helpful and important to provide.

Additional Notes

I don’t have Island Code because my map is still in progress and not published!

I found it my self. It was one little thing from the last custom asset that I put. It was nothing in the contect browser and nothing when I place it down, even had no texture no anything so I thoud my self that the crash is probably from it plus It’s littery nothing so let’s delete it and I did and my map finally worked again!!! YES!!!
