App keeps crashing whenever I try to open a specific item. I have previously read and annotated this item successfully. Behaviour is persisting even after a restart of the device (which I was forced to do as it caused the whole device to become responsive). I have tried a number of times with this item and it keeps happening. Other items are behaving normally when I open them. When I reopen the app after it crashes and closes, it opens the last successfully opened item, not the one which crashed it.
