So OnAppearing(), I am calling InitializeComponent() as you can see in a below details.

public Settings(Item selectedItem)
{
    
}

protected async override void OnAppearing()
{
    base.OnAppearing();
    Items = new ObservableCollection<Item>();
    Items1 = new ObservableCollection<Item>();
    await Task.Delay(500);
    InitializeComponent();
    InitializeItemsH();
    InitializeItems();
    BindingContext = this;
} 

when I get back to this page by navigating from another page. the app is getting crashed on IOS and windows (start without debugging). [on windows debugging its totally working fine]

as I have used InitializeComponent() here for clear the stack so function will be clickable.

you can check below XAML.
My XAML Page

I have try run the page without frame its totally working fine, but whenever I uncomment the frame component app gets crashed. don’t get understand why its working on IOS and Windows[start without debugging]
