    Hi Everyone!

    I’ve been banging my head on my desk for the last few weeks as I try to figure out what’s going wrong with my game. Long story short my game was originally built with Unity 2020.3.12f1 and used Xcode 14 to build to my iPhone (13 pro). Last month, in order to build to iOS 17 I had to update to Xcode 15.2. Once I did that, my game began crashing when I tap a button that simply loads my "main menu” scene. The only function attached to that button is: SceneManager.LoadScene("Main Menu”);.

    Code (CSharp):
    1. SceneManager.LoadScene("Main Menu”);
    It’s also worth noting that this only happens on my iOS build and does not happen at all in the Unity editor. Everything works perfectly in the editor and worked perfectly on my iPhone until I updated to Xcode 15. There are also no errors in the unity console.

    So to troubleshoot, I updated my Unity version to 2022.3.18f1 and attempted to build using Xcode 15.2 again, and the same crash happens. When that button is tapped, my game freezes and the Xcode console only reads:

    libc++abi: terminating due to uncaught exception of type Il2CppExceptionWrapper


    Once the error pops up in Xcode I get the following:

    When I attempt to stacktrace in Xcode I get the following:

    I can’t figure out for the life of me what’s causing this crash. Can anyone help me troubleshoot this so I can figure what is causing this crash and hopefully solve it?

    Thank you!
