Deploy the ManualMauiTests project on Android and navigate to the two I CollectionView scenarios named in the report. Reproduce vertical scrolling, capture the complete exception beyond the listed Mono.Android stack frames, and trace the affected behavior until both variable-sized and grouped DataTemplate lists scroll without throwing.
