This seems to happen also on iOS 26.2.1.
Remove user specific paths in xcconfig (apple#82)

One of our users is experiencing a similar issue with
GKLocalPlayer.Local.FetchSavedGames()on iOS 26.6.1 (Unity 6000.3.11f1, Apple.GameKit 3.0.2). The returned Task remains pending without a result or exception, blocking startup.Reinstalling the app and signing out of Game Center did not help. Could this be related to the issue reported here?

@kyubuns it could be. One thing that would be worth doing is getting native logs with Feedback Assistant. I believe this is not unique to the Unity plugins.
