Main UEFN Project lost locally but island still live - Is recovery possible?

Summary

Hello, I urgently need assistance. One of my main published UEFN islands used for revenue has suddenly corrupted locally. The main .uefnproject file is now only 13KB and the map UMAP cannot be opened anymore.

The island is still LIVE and playable inside Fortnite, but I cannot open or restore it inside UEFN anymore. This is a critical revenue impact for me.

I need access to an older cloud revision / restore of the project from Epic side (the same version that is currently live / published).

Can you please escalate this to the UEFN technical team for “Lost Project State Recovery”?

Island name: VIBEPLACE
Owner codenamed account: etnlina

This is not a normal support question. This is a live revenue island and the local project got corrupted.

I need the UEFN cloud state that matches the current published version restored or provided.

Steps to Reproduce

  1. Work normally on a UEFN project (Project Name: VIBEPLACE)
    2. At some point, the project folder was on OneDrive (I later disabled OneDrive)
    3. After restarting PC + UEFN, my .uefnproject file suddenly became 13 KB
    4. When trying to open the project again inside UEFN, I get plugin duplicate error / project cannot be loaded
    5. I can still PLAY the island in Fortnite and the island is still LIVE, but I cannot open the project file anymore locally because it is now corrupted

Expected Result

UEFN should load my project locally and the .uefnproject file should not randomly become 13 KB corrupted.
I should be able to continue editing my published island.

Observed Result

The .uefnproject file is now only 13 KB and cannot be opened.
I receive plugin duplicate errors and UEFN will not load the project at all.
My island still exists online and is playable in Fortnite, but I cannot access or open the project locally to update it anymore.

Additional Notes

I cannot find a valid autosave with a working .umap either.
Is there any way you can recover / restore the most recent version of my island from Epic’s side since it is currently still published and playable in Fortnite?
