Description

I make a NavigationPage that navigates to a Shell. When I press the back button on my Android device, it crashes the app. It works on Windows.

Steps to Reproduce

  1. Create a new .NET Maui app

  2. Create a ContentPage with a button to navigate to a new AppShell

  3. Change the App.cs to this:
    public App()
    {
    InitializeComponent();

         MainPage = new NavigationPage(new ContentPageExample());
 }

  4. Now, when the app starts in the ContentPage, you can navigate to the Shell. But when you press back on Android, it crashes. With Windows it works.
