Same problem. My collection screen locks up the game. Unfortunately this means the game is unplayable because if we can't look at our collections we can't do much.
Hey - this should now be resolved, patch info is available here: https://thestrangest.itch.io/shadow-gadget/devlog/441572/shadow-gadget-114b-ghos...
Make sure to redownload the game from itch.io and sideload it through Panics side: https://play.date/account/sideload/
