I believe this also affects net7.0-maccatalyst, as I'm seeing the same issue when building under dotnet 7.0.309.

If you simply add the DisplayActionSheet to the OnCounterClicked handler of the standard Maui app the action sheet does not appear and following statements are not executed. On Windows and Android this works as expected. I also suddenly have in my app when running on MacCatalyst MenuBarItems in my XAML that do not respond when clicked. I have a feeling these problems are related.

private void OnCounterClicked(object sender, EventArgs e)
{
	count++;

	this.DisplayActionSheet("What type of condition?", "Cancel", null, "Source Condition", "Position Condition", "Attribute Condition", "Affected By Condition");

    if (count == 1)
		CounterBtn.Text = $"Clicked {count} time";
	else
		CounterBtn.Text = $"Clicked {count} times";

	SemanticScreenReader.Announce(CounterBtn.Text);
}

I ran into the same issue, and was getting the following null reference exception, .NET 7.0.401

await Application.Current.MainPage.DisplayActionSheet("Title", "Cancel", null, "test", "test1", "test2");

When I run the standard Maui app described above, with or without the change, it outputs this message when it starts up. It seems DisplayActionSheet is getting called from somewhere and already reporting a problem.

I was seeing this message before I had issues with DisplayActionSheet, though.

[cdavidyoung]

Yes, but perhaps it was trying to tell us something. I would think that warning should be fixed in any case and perhaps it will resolve this problem.

@Matthewrbowker One more datapoint is that DisplayAlert seems to work fine. I suppose I could convert the DisplayActionSheet in my app to a series of DisplayAlert but that would be rather awkward. : ) Besides that, the other thing that is not working for me are MenuBarItems. I have a feeling that when DisplayActionSheet is fixed it will fix MenuBarItems as well.
