Riproduci il crash con il MaterialMenuButton mostrato in MainPage.xaml, quindi esamina XF.Material/UI/MaterialMenuButton.cs in OnViewTouch intorno alla riga 131 e la chiamata da OnButtonClicked. Conferma che Choices popolati visualizzino il menu invece di generare l'eccezione segnalata sia su Android sia su iOS.
