I was experiencing a nagging issue with a UWP ListView object that resulted in an unhandled exception and crashed the app. The error wasn't related to any method I was handling, so I couldn't trap it. I had to do a painstaking process of elimination of the XAML code. Ultimately I found the issue was related to my GridView's (I am using a ListView inside a GridView) ScrollViewer.VerticalBarVisibility. I had to set it to "Disabled".
