I think the bug probably started occuring with this commit 720c25c

It only happens with ItemsUpdatingScrollMode="KeepLastItemInView"
the two other values for ItemsUpdatingScrollMode does not trigger this bug.

From the following callstack at the moment of the crash it seems
the crash appears when rendering the CarouselItemView for the first time (creation of the renderer)
during CarouselViewRenderer.UpdateItemsSource() it will call base.UpdateItemsSource() (from ItemsViewRenderer)
(this call to base.UpdateItemsSource() comes just before setting the _itemsSource on the CarouselViewLoopManager,
so until this base.UpdateItemsSource the _itemsSource in the LoopManager will remain null)

but during the call to base.UpdateItemsSource() , will at some point call UpdateItemSpacing() that will in turn call
CarouselViewLoopManager.GetGoToIndex (CarouselViewRenderer.cs:721) (at this point the _itemsSource is accessed before being set to a non-null value)
(through an native android callback AndroidX.RecyclerView.Widget.RecyclerView+AdapterDataObserver.n_OnItemRangeChanged_II so maybe a little unexpected ? )

So the whole bug seems like an initialization order problem to me.

Workaround

using the default value for ItemsUpdatingScrollMode (although it may have a different behavior)

also downgrading to 2401 also works
