“Publishing Error” in Creator Portal on a FIRST-EVER release, but the content
review approval email arrives afterward. The island has never gone live, so no
island code exists yet.

This looks like the same failure as FORT-1084657 and the report at

Summary Summary: I’m experiencing a publishing error in UEFN. Every time I submit a new release, I receive a “Publishing Error” in the Creator Portal. However, shortly after, I receive an email confirming the version was approved. Despite the approval email, the update never goes live. I have already tried: Creating multiple new private versions Making small changes before resubmitting Changing the project version number Clearing browser cache and switching browsers This seems related to ti…

Important difference: existing reports are all about UPDATES to already-published
islands, and one poster suspects brand-asset switching (Star Wars / Squid Game)
as the cause. My case has neither — this project has never been published, and it
has never used or removed any brand assets. That may help narrow the root cause.

Steps to Reproduce

1. Push the project from UEFN (v[XX.XX]). Publishing Report passes with no issues.
2. In Creator Portal, create the first release from that private version.
3. Fill in Game Details / Rating and submit for content review.
4. Creator Portal shows a publishing error.
5. Receive an email stating the version passed content review / was approved.
6. Creator Portal remains in the error state. The island never goes live and no
   island code is issued.

Expected Result

The approved release goes live and an island code is issued for the project.

Observed Result

Creator Portal stays in an error state despite the approval email.
The island has never been published, so there is no island code to provide.

Adding a possible common factor: my project makes heavy use of NPCs (NPC Spawner devices / NPC character definitions).
Another report today ( Publishing Error ( urgent please help ) ) lists “add npc → run memory calculation → create release” as the repro steps. Combined with my case (first-ever release, no brand assets, NPC-heavy), NPC content may be a better lead than the brand-switching theory.
