Sorry if it's not clear, I'm using Google Translate. My problem is that today, after using the backpacks for a long time, whenever a player wants to open his backpack, it appears empty and that error appears, apart from creating a backup file, how can I recover the things I had???

Steps to reproduce
open a backpack
