FYI I just found another bug report someone posted on the wrong forum, so this issue seems to be more widespread than just me. I also see 3 people on the UEFN Discord server reporting the same problem.

In-Island Transactions Failed open in new window You can't create a new release with this version because it has in-island transaction errors. Create a new version in UEFN that resolves the issues, then try again. Issues and Bug Reporting (Unreal Engine)
