with this code I got the message "System.Exception: Set property 'System.Windows.ResourceDictionary.Source' threw an exception," I am developing in Revit Api 2023

Version

5.2.1

Start with the embedded WPF XAML in TestView and reproduce the ResourceDictionary.Source exception in Revit API 2023 with MaterialDesignThemes.Wpf 5.2.1. Check the referenced pack URI and resource availability; done means TestView loads without the exception.
