Windows Phone app crash on device

Question

I make installed app on windows phone which crash but when I run in windows emulator it did not crash

I have button where I load page which have browser and I try to load there

• Code for button click

  private void Button_Click(object sender, RoutedEventArgs e)
  {
      QueryString queryString = new QueryString { Parameter = "http://www.example.com/en/about" };
      App.RootFrame.Navigate(typeof(WebViewPage), queryString); 
  }
  

• onNavigatedTo of other Page

  protected override void OnNavigatedTo(NavigationEventArgs e)
  {
      QueryString param = e.Parameter as QueryString;
      Uri uri = new Uri(param.Parameter,UriKind.Absolute);
      webView.Navigate(uri);
  }
  

Not only it is happening with webview but also it is also happening with ListFlyOut control.

I don't know what is the issue but it is crashing on the device.

I just reset my Windows Phone and install again my app, voila all start working. With much better performance.
