I already posted this in the comments, but I wanted to leave this here as well in case anyone else runs into it. The only way to avoid is to not run while opening chests as far as I know. I can make a video clip if needed!

1.4 reintroduced an old vanilla bug into your mod. If you're running and hit "take all" the game will crash around half the time. It's reproduceable on a new character as I did here: https://pastebin.com/WsKP2XTs Considering that this is a bug that vanilla used to have, it's hopefully an easy fix.
