Summary
Since Data Layers were patched in a recent release, I can open connected sessions and play the game but can’t open new Private Islands. At the start of the 2nd Round when unloading Round 1 Data Layers and loading round 2 Data Layers, FPS Drops significantly for a few seconds. I’m blocked from releasing updates at this point. Please help!

Steps to Reproduce
Load project in UEFN and Launch Session. Start game and play through Round 1 (or use built in shortcut - see video). Watch FPS when Round 2 starts. End game. Launch Memory calculation from UEFN. Memory Calculation successful. Attempt to open Private Island code in-game (will not load). Submit version for approval with no changes to name, description, assets, rating, or attributions.
Expected Result
Round 2 starts with no FPS drop. Private Island loads and is playable. Submission is approved.
Observed Result
Round 2 starts with a 1-2 second massive drop in FPS. Private Islands codes since the Data Layer patch are unloadable, but connected UEFN+Fortnite Creative sessions work fully and are playable. Submissions since patch are all rejected. I’ve been guessing it’s the FPS but moderation has been less than clear on the issue.
