GameCenter crash starting iOS 16.4.1

Hello,

Our game has been released since 2020, and we recently started seeing a crash starting with iOS 16.4.1. We're having trouble reproducing it, it only seems to happen on brand new devices with GameCenter accounts that have not run our game before, it seems to me the first time the game tries to make a save. We just got our hands on a pair of new devices and still cannot reproduce the crash.

My knowledge of Obj-C is exactly zero, so it's difficult for me to know what's really going on here. I've attached the crash log and a screenshot of what I believe is the file and line pointed to in the crash. From what little I can tell, it might just be that the function on line 58 is missing an extra argument as with the one on line 63, is it possible it's that easy? Is it possible that's something that's changed starting with 16.4.1?

Any help is appreciated!
