Didn’t help me, but maybe it can help you…

Did you have any plugins for that project? I had a few, but none that should have been causing an issue like this as I understand it. All my other projects using the same plugins work fine in UE5 with UE5 versions of the plugins

Documentation says: UE5 Early Access projects does not supports on UE4 / UE5 released versions.

I solve my problem with manually repeating all blueprints on UE5 project. Only blueprints. All other assets works fine.
