IOS13 crash while changing ItemsSource property in modal page

Hello!

Thanks for the excellent control. Until a certain time, there were no problems with its use, however, either after switching from PCL to .NET Standart, or after updating its version, there was a problem with iOS13.

Description

If a window with the specified component is opened through the following construction, an error occurs: await Navigation.PushModalAsync (Page);

I saw in issues that opening a window through Application.Current.MainPage = new PageWithAutoSuggestBox … solves the problem and it really solves it.

However, the use of modal windows is fundamental in our project. Hope it it’s not a hard job to fix this and this controll will be better.

Steps to Reproduce

1. Create page with AutoSuggestBox
2. Open page with await Navigation.PushModalAsync (Page) method
3. Enter 2 or 3 symbols in AutoSuggestBox to fire private void TextChanged(AutoSuggestBox sender, AutoSuggestBoxTextChangedEventArgs e) event
4. Set ItemsSource in this event
5. Get error and app crash

Basic Information

• Version with issue: 1.01
• IDE: Visual Studio 2019 for OSX
• Platform Target Frameworks:
  • iOS: 13.X

There’s no need to recompile. You can select a newer version of forms to use. 3.1 is merely a minimum
