Recover my original maps

I recently got a new PC and transferred my Unreal Editor for Fortnite (UEFN) setup. After signing in with my Epic Games account, I can see the names of my previous UEFN projects in the Project Browser, but when I open them, the islands appear empty — all of my previous work (landscape, props, devices, etc.) is missing.

I would like to know if there is any way to recover my original maps or files from Epic’s servers, especially if they were previously uploaded or synced with my account.

Hi again Molon, I responded to the duplicate thread on this.
