To reproduce issue you can use https://github.com/jacek-marchwicki/twoway-view/tree/bug1-reproducer Go to staggered item tab and scroll to the down of the list, a little up, down.. and should be quite easy to reproduce.

i'm facing the same problem as well. Could it be because of the handleAdapterChanges method which clears the entries cache?

FYI: I've fixed this specific crash in 7e24609f58a38dc623c5acb8a797e2fc5e8847be but I'm still seeing crashes for a different reason. Keeping this open for now.
