Hello @aykutsahin,

Thanks for reporting this. I’ve found your issue and will prepare a fix for the next UEFN release.

One of your changes is name clashing with a version that is already submitted.

On your end, start with backing up your project directory.
Then, in UEFN, in the ‘Submit Files’ dialog you should ‘right click’ and ‘revert’ individual files until your submit succeeds.
