MAUI iOS just hangs on refresh of data

Question

I have redeveloped a Xamarin Forms app into .NET MAUI and it was working fine until recently. I have two problems, but will post the other problem into a different question.

For this problem, when pulling down to refresh the data the app just hangs on UIApplication.Main(args,null, typeof(AppDelegate));

It never gets past that point. Has anyone come across this problem and how did you solve it?

 public class Program
 {
     // This is the main entry point of the application.
     static void Main(string[] args)
     {
         // if you want to use a different Application Delegate class from "AppDelegate"
         // you can specify it here.
         IAccount existingAccount = Task.Run(async () => await PublicClientSingleton.Instance.MSALClientHelper.InitializePublicClientAppAsync()).Result;
         UIApplication.Main(args, null, typeof(AppDelegate));
     }
 }

Answer 1

Hello,

.Result is used to synchronously wait for the task to complete, and you put the method in Main function, so the app hangs on.

I noticed that this PublicClientSingleton.Instance.MSALClientHelper.InitializePublicClientAppAsync() method is to initialize the MSAL client app, I added the Microsoft Authenticator tag to let them focus on this thread and support further.
