I think related to this, I am seeing the following issue with both macOS and iOS using the latest dotnet version:

/namespace/Platforms/MacCatalyst/CustomControls/CustomButtonHandler.cs(29,29): Error CS0115: 'CustomButtonHandler.ConnectHandler(UIButton)': no suitable method found to override (CS0115)

    protected override void ConnectHandler(UIButton platformView)
    {
        base.ConnectHandler(platformView);

        platformView.Layer.CornerRadius = 3;
        platformView.Layer.BorderWidth = 2;
        platformView.Layer.BorderColor = Colors.Transparent.ToCGColor();
    }

This was working fine beforehand with dotnet 8.0.0

This should be the same underlying issue involved with both.
