How to debug Microsoft.UI.Xaml

[SeRgI1982]

In our project we use WinAppSDK in version 1.2.230118.102
I see many weird issues during working with the app:

Exception thrown at 0x00007FFEA697441C in App.exe Microsoft C++ exception: winrt::hresult_error at memory location ...

It hapens when I try to close TabItems (each TabItem contains NavigationView which is bounded to a collection in ViewModel).

Callstack shows me that it happened here: NavigationViewItem::UpdateVisualStateForChevron()

Honestly, when we started test stronger our app before MVP release, a lot of smiliar issues appeared and we have decided to do something with this instead of waiting for fixing bug in a newest version of Microsoft.UI.Xaml

How to fork correctly Microsoft.UI.Xaml and attach instead of nuget package ?

We would like to report bugs but in the meantime fix them (contribute) and give our app chance to work without crash.
