What happened?

I'm assuming VSCode or Windows Terminal installed the Cascadia fonts (I have Code and Mono). Recently, running the latest release of https://github.com/lucasg/Dependencies resulted in an unhandled exception. Likewise, going to Start->Font Settings and clicking on the Cascadia Mono font results in an unhandled exception in SystemSettings.exe. I uninstalled all Cascadia fonts, downloaded the ttf and installed them again 'For all users' but the issue remains. In the Dependencies code it can be seen that the exception occurs when calling GetTypefaces on the FontFamily instance for Cascadia Code.

Code to reproduce:

            foreach (var family in System.Windows.Media.Fonts.SystemFontFamilies)
            {
                foreach (var typeface in family.GetTypefaces())
                {
                }
            }

Exception message is "UnauthorizedAccessException: Attempted to perform an unauthorized operation."

Call stack:

   at MS.Internal.Text.TextInterface.Native.Util.ConvertHresultToException(Int32 hr)
   at MS.Internal.Text.TextInterface.FontList.get_Item(UInt32 A_0)
   at MS.Internal.FontFace.TypefaceCollection.Enumerator.get_Current()
