Game crashes on IOS after enabling push notifications.

For android I had this script setup for mobile push notifications :

void Start()
{
    DontDestroyOnLoad(gameObject);
    startNotifs();
}

private async void startNotifs()
{
    try {
        AppleManager.instance.AppendAppleLog("reached 1");
        await UnityServices.InitializeAsync();
        AppleManager.instance.AppendAppleLog("reached 2");
        bool userGaveConsent = true;

        if (userGaveConsent) {
            AnalyticsService.Instance.StartDataCollection();
        }
        AppleManager.instance.AppendAppleLog("reached 3");

        try {
            AppleManager.instance.AppendAppleLog("reached 4");
            string pushToken = await PushNotificationsService.Instance.RegisterForPushNotificationsAsync();
            AppleManager.instance.AppendAppleLog("push notif token : " + pushToken);
        }
        catch (Exception e) {
            AppleManager.instance.AppendAppleLog("Failed to retrieve a push notification token. " + e);

        }
    }
    catch (Exception e) {
        AppleManager.instance.AppendAppleLog("Failed push notif setup : " + e);
    }

}

The AppendAppleLog is my own way of logging for ios on my ubuntu vps, you can imagine it as Debug.Log

For android it works perfectly. On IOS it didnt work, all I could get was to "reached 4" and then nothing, the try catch blocks don't continue, i get no errors. I realised that in xCode project the Push notifications in signing and capabilities wasn't added. After adding it and testing the game through testflight, the game crashes either immediately on launch or after pressing allow for push notifications.

On unity cloud the project seems to be setup correctly with apple keys added and sandbox turned on.

I could reproduce this on Iphone X and iphone XS. Unity version : 2022.3.10f1 push notifications package version : 3.0.1-pre.1 Xcode version : 15.3

Here is the crash log:

In xcode viewing the stack trace, this is the last place i can view :

void AppController_SendNotificationWithArg(NSString* name, id arg)
{
    [[NSNotificationCenter defaultCenter] postNotificationName: name object: GetAppController() userInfo: arg];
}
