Research direction

Start at Wpf.Ui.Appearance.Theme.Apply and follow the stack through Accent.ApplySystemAccent, Accent.GetColorizationColor, and Wpf.Ui.Interop.UnsafeNativeMethods.GetDwmColor. Reproduce on Windows 10 with .NET 6 and WPF-UI 2.0.3; done means Theme.Apply completes without the FileNotFoundException and the theme is applied.
