Exception when adding Ribbon to RibbonWindow

[Timothy D Jones]

I just updated to Essential Studio for WPF 20.3.0.56, and I'm using the weekly build for WPF 20.3.0.59. 

I am just starting a new application in Visual Studio 2022 Community Edition using Prism & Syncfusion. After configuring for a RibbonWindow and setting up the namespaces in xaml, I pulled a Ribbon control from the toolbox, and dropped it into the window.

After adding the Ribbon, I am getting an unhandled exception "#FFD2D2D2 is not a valid calue for property 'SeparatorColor'.  Nothing has been added to the Ribbon, and no customization has been added to the window with the exception of SfSkinManager to use a Office 2019 theme. 

I have no idea where this exception is actually coming from, and help would be appreciated. 

I have copied the call stack below, and attached a zip of my current Visual Studio Solution.

Reverting back to Syncfusion.SfSkinManager.WPF 20.3.0.56, Syncfusion.Tools.Wpf 20.3.0.56, and Syncfusion.UI.WPF.NET 20.3.0.56 removes the exception. 

Unfortunately, that doesn't resolve the issue with the recent builds.
