Cannot transfer one UEFN project between teams I own — cannot_transfer

Summary

One specific UEFN project cannot be transferred between two teams that I own in Creator Portal.

I am the Owner of both teams. Other projects transfer successfully between the same teams, but this project fails with the following error:

[DEP] Backend dependency returned unexpected error errors.com.epicgames.content-service.cannot_transfer

Closing UEFN and Fortnite and refreshing Creator Portal did not resolve the issue.
