(WinUI 3) Visual State Manager throwing System.Runtime.InteropServices.COMException
I use the VisualStateMangaer.GoToState() method twice, with the same parameters. Strangely, it only works in one of the situations and throws an exception in the other. What am I missing here? 
c#
private void DialogLoaded (object sender, RoutedEventArgs e)
{
    VisualStateManager.GoToState(this, InternetConnected() ? "IsbnEnabled" : "IsbnDisabled", false);
    // This works perfectly fine.

    NetworkInformation.NetworkStatusChanged += delegate
    {
        bool connected = InternetConnected();

        VisualStateManager.GoToState(this, connected ? "IsbnEnabled" : "IsbnDisabled", false);
        // This one throws a System.Runtime.InteropServices.COMException with no message.
    };
}
