The type of exception cannot be obtained from unhandled exception event handler

        public App()
        {
            this.InitializeComponent();
            UnhandledException += OnUnhandledException;
        }

        private void OnUnhandledException(object sender, Microsoft.UI.Xaml.UnhandledExceptionEventArgs e)
        {

        }

    public sealed partial class MainWindow : Window
    {
        public MainWindow()
        {
            this.InitializeComponent();
        }

        private void myButton_Click(object sender, RoutedEventArgs e)
        {
            throw new KnownException("LOB Warning");
        }
    }

    public class KnownException : Exception
    {
        public KnownException(string p_message)
            : base(p_message)
        {
        }
    }

I have already reported this issue, why was it deleted?
Thanks.
