Unable to transfer UEFN project to another team

Summary

I am unable to transfer my UEFN projects to another team I belong to and receive the error message “[DEP] Backend dependency returned unexpected error errors.com.epicgames.content-service.cannot_transfer” I have already tried using an incognito browser window, as suggested in a support article, but this did not work either.
I also tried contacting support but nobody there knew a solution either.
