TaskDialog Crash

[ClaudiuHBann]

Hello I am using the last version of Avalonia which is 11.0.6 and FluentAvalonia 2.0.4 and I am trying to make a TaskDialog in C# code in a UserControl view like:

        var td = new TaskDialog { Title = "Title", Content = "Content",
                                  Buttons = { TaskDialogButton.YesButton, TaskDialogButton.NoButton },
                                  XamlRoot = VisualRoot as Visual };
        _ = await td.ShowAsync();

and I get an exception:

   at FluentAvalonia.UI.Controls.TaskDialog.TrySetInitialFocus()
   at FluentAvalonia.UI.Controls.TaskDialog.<ShowAsync>b__6_1(Object s, EventArgs e)

Is there something specific I need to do in order to solve this issue?
