Fabric, latest release of Traveler's Backpack (10.4.10)

When equipping a backpack which had a few upgrades added and items inside, my game crashes. Nothing is wrong with the backpack, as the backpack can open normally when it's off. When I reboot, the backpack is not on. The game does not quit, but simply freezes up indefinitely.

Right click in the air with the backpack in main hand to open, then click "Equip Backpack."

I've only used singleplayer, haven't tried multiplayer with the latest version yet.

Crash reports:
crash-2025-04-11_11.31.23-server.txt
crash-2025-04-11_11.31.26-client.txt

try re equipping backpack upgrades, I will release fix to prevent this soon.

it seems the problem is the Feeder upgrade, my game crashed as soon as I picked it up (clicked it in the inventory) to reequip it. Otherwise, reequipping the other ones worked fine.
