Heya, thanks for trying it out! That's completely fair, all of us were learning how Godot 4 specifically works in comparison to Godot 3, and we did spend up to the last minute working on stuff, so bugs inevitably slipped through the cracks. Playing through a bit before pushing a tiny update, I did notice our player's animations lock up after interacting with the shop in one level, but I wasn't able to consistently get it to happen enough to pinpoint a definitive fix yet, but it's definitely something for us to investigate.
