Gamecenter related crash in Unity

Trying to figure out a particularly odd crash report.

Crashed: com.apple.root.user-initiated-qos.cooperative
0  GameCenterFoundation           0xe2054 __swift_project_boxed_opaque_existential_1 + 19952

2  libswift_Concurrency.dylib     0x42868 swift_job_runImpl(swift::Job*, swift::ExecutorRef) + 72
3  libdispatch.dylib              0x15944 _dispatch_root_queue_drain + 396
4  libdispatch.dylib              0x16158 _dispatch_worker_thread2 + 164
5  libsystem_pthread.dylib        0xda0 _pthread_wqthread + 228
6  libsystem_pthread.dylib        0xb7c start_wqthread + 8

We're using Unity 2021.3.16f1, we haven't touched the gamecenter login code for ages but this error started happening. It looks like it's only appearing on iOS 16.4 and subversions.

Same issues here on Unity 2020.4.40.f1. Can confirm that it only happens on ios 16.4 and above

Another people also reported on the forums https://forum.unity.com/threads/gamecenter-login-crash-since-16-4-1.1431688/

No updates other than it continues to happen and continues to be a 16.4 only issue.

I am also facing a similar issue. We are using GameCenter for Highscore and Leaderboard.

We're only using it for a platform login option. It does look like the crashes are all happening when the app is backgrounded. Can anyone else confirm that?

For people following this with the release of iOS 16.5 it seems like whatever was the problem was on Apple's side and is fixed.

Still seeing the crash on 16.4.1 devices but only on 16.4.1 and the total rate has gone down significantly.
