Can you show a little more code that actually shows the dialog? How do you do that?

My suspicion is that it runs on a background thread or something and you'll need to maybe use this. Have you tried the Dispatcher and did that change the behavior at all?

@jfversluis I have tried this solutions with Dispatch and without also. Please review

1. Application.Current.MainPage.Dispatcher.Dispatch(async` () =>
                  await DisplayAlert("Confirmation", "Hello", "cancel")
                );

2. var taskCompletionSource = new TaskCompletionSource<bool>();
                var alertController = UIAlertController.Create("Confirmation", "Are you sure you want to close the app?", UIAlertControllerStyle.Alert);
                alertController.AddAction(UIAlertAction.Create("Yes", UIAlertActionStyle.Default, action => _commonEventhandlerService.InvokeSaveEvent(true)));
                alertController.AddAction(UIAlertAction.Create("No", UIAlertActionStyle.Cancel, action => _commonEventhandlerService.InvokeSaveEvent(false)));
 
                UIApplication.SharedApplication.InvokeOnMainThread(async () =>
                {
                    await UIApplication.SharedApplication.KeyWindow.RootViewController.PresentViewControllerAsync(alertController, true);
                    taskCompletionSource.SetResult(true);
                });
 
                // 6. Wait for the task completion source
                var presentationSuccessful = await taskCompletionSource.Task;
 
                // 7. Code to execute after successful/failed presentation (optional)
                if (presentationSuccessful)
                {
                    _appOperationService.ShutDownApplication();
                }
                else
                {
                    // Code to handle failed popup presentation (optional)
                }

I think you need to create a small repro project for what you're trying to do. From the looks of it, you're calling into straight UIKit code for showing your dialog, which is fine to do but that's not really a MAUI UI issue or bug.
