### Summary Problem with Launching Memory Calculation After starting this process, it gives me the map code, but after I press the DONE button, it kicks me out of the Fortnite session, and Launching Memory Calculation lasts forever. I waited for an hour, but it still didn’t complete. The screenshots show my memory usage on the island and what happens after I click the DONE button after receiving the code. There are no errors with the Verse code or other errors on the map that could interfere with this. If anyone has encountered this problem, I would appreciate your help! ### Please select what you are reporting on: Unreal Editor for Fortnite ### What Type of Bug are you experiencing?

Yes, I have the same problem. After the update, I can’t even figure out what is taking up this memory, because everything was fine before the update. ---
