Research direction

Start with the simple demo project's MainWindow.xaml and reproduce the crash using WindowStyle="None" and AllowsTransparency="True" on WPF UI 3.0.0 under Windows 10, .NET Framework 4.8, and VS2019; compare the behavior with WPF UI 2.0.3. Done means the window starts without the WindowStyle exception and the AccentFillColorDisabled resource error is resolved or explained.
