在Azure中使用集线器注册推送通知时，Xamarin.iOS本机崩溃错误SIGSEGV

Question

我正在Xamarin应用程序项目的iOS项目中使用此方法向Azure的通知中心注册以进行开发（将集线器和应用程序配置为通过证书开发并在Apple开发人员门户上进行配置，即entitlements.plist中的关键字设置为开发人员，中心已上传了p12开发人员证书）。

[此方法（以及相应的应用程序）在开发模式下的iPhone 5S上运行良好。

但是在我的iPhone 8 Plus上却出现此错误：

在AppDelegate.cs中：

public override void RegisteredForRemoteNotifications(
            UIApplication application, NSData deviceToken)
        {
            AzureNotifHub = new SBNotificationHub(AppConstants.AZURE_DEVNOTIFHUB3_LISTENSHARED, 
  AppConstants.DEV_NOTIFHUB3);

            // update registration with Azure Notification Hub
            AzureNotifHub.UnregisterAllAsync(deviceToken, (error) =>
            {
                if (error != null)
                {
                    Debug.WriteLine($"Unable to call unregister {error}");
                    return;
                }

                var tags = new NSSet(AppConstants.IOSSUBSCRIPTIONTAGS.ToArray());
                AzureNotifHub.RegisterNativeAsync(deviceToken, tags, (errorCallback) =>
                {
                    if (errorCallback != null)
                    {
                        Debug.WriteLine($"RegisterNativeAsync error: {errorCallback}");
                    }
                });

                var templateExpiration = 
 DateTime.Now.AddDays(120).ToString(System.Globalization.CultureInfo.CreateSpecificCulture("en- 
 US"));
                AzureNotifHub.RegisterTemplateAsync(deviceToken, "defaultTemplate", 
 AppConstants.IOS_APNS_TEMPLATE_BODY, templateExpiration, tags, (errorCallback) =>
                {
                    if (errorCallback != null)
                    {
                        if (errorCallback != null)
                        {
                            Debug.WriteLine($"RegisterTemplateAsync error: {errorCallback}");
                        }
                    }
                });
            });

我现在正在开发模式下使用iPhone 8 Plus。该设备已从应用商店下载了该应用，因此先前已在生产模式下向通知中心注册，不知道这是否与它有关。

也正在使用BETA ios 13操作系统。

什么可能导致此错误以及如何解决？

该问题似乎是由于this造成的
