ItemTemplate of null causes unhandle exception on WinUI #51
Description
After updating my MAUI App from .net8 to .net9 i ran into unhandled exceptions, thrown in App.g.i.cs while debugging my App.
Thhis happens, when i navigate back from a page containing a VirtualListView.
It seems like the ItemTemplate in the ItemsRepeater cannot be null.
When we do not define an ItemTemplate at all in our view, some unhandled exception is thrown as well.
I attached a minimal reproducable example, where this issue is reproducable.
