MediaElement.Crash.Demo (iOS)

Minimal .NET MAUI (.NET 9) reproduction showing an iOS-only crash when using a MediaElement inside a CarouselView DataTemplate without Shell navigation.

Overview

This app intentionally removes Shell to keep the navigation stack minimal and surfaces an iOS crash related to MediaElement usage in a templated control.
Android (and likely Windows/MacCatalyst) run without crashing; iOS reproduces the fault.

Error:

{System.InvalidOperationException: Cannot find current page   
at CommunityToolkit.Maui.Core.Views.MauiMediaElement..ctor(AVPlayerViewController playerViewController, MediaElement virtualView) 
in /_/src/CommunityToolkit.Maui.MediaElement/Views/MauiMediaElement.macios.cs:line 57   
at CommunityToolkit.Maui.Core.Handlers.MediaElementHandler.CreatePlatformView()

Key Points

• App overrides CreateWindow to return a NavigationPage instead of using Shell.
• MainPage contains a CarouselView whose ItemTemplate is a very simple MediaElement bound to a list of three remote MP4 URLs.
• Crash occurs only on iOS. The same code path does not crash other platforms (based on current observations).
• Wrapping the MainPage in a NavigationPage permits exception capture/visibility; using plain new Window(new MainPage()) more directly exposes the failure scenario.
• The scenario highlights a potential issue with MediaElement lifecycle inside a recycled templated control (CarouselView).
