We found out that the earlier change to x:Reference causes System.Xaml.XamlObjectWriterException to occur internally in XAML.
With some further digging we found in the documentation on https://learn.microsoft.com/en-us/dotnet/desktop/xaml-services/xreference-markup-extension?redirectedfrom=MSDN:
x:Reference is a construct defined in XAML 2009. In WPF, you can use XAML 2009 features, but only for XAML that is not WPF markup-compiled. Markup-compiled XAML and the BAML form of XAML do not currently support the XAML 2009 language keywords and features.
Thought the x:Reference at first glance seems to work it creates internal exceptions within XAML, therefore it is probably wise to revert it back.
