Summary

I converted my island, but reverted it back to FNC because of an error I got when trying to “Launch Session”.
Now it works normally again in FNC.
But I no longer have the option to “convert” the island again, instead I can open the UEFN-project, which now behaves like a duplicate of the island.

Steps to Reproduce

Import/convert FNC island to UEFN & revert it back to FNC.

Expected Result

I want to convert the island from FNC to UEFN again.

Observed Result

I no longer have to option to convert the island.

Platform(s)

Additional Notes

The Error when I try to Launch session says “Failed to stage project for upload. Failed to resolve plugin file for module (a855202a-2a7c-44d4-b4ea-6658a058fa1d)”
