Research direction
Start from the reported IllegalArgumentException when loading multiple item types and trace the ItemViewDelegate matching path, especially isForViewType. Reproduce the position=3 case with a multi-item data source, then determine why no delegate matches and verify the corrected behavior with a regression test.
