To Reproduce
Steps to reproduce the behavior:

1. Make sure the backpack has a sleeping bag
2. Place the backpack
3. Sleep
4. Try to re-equip the backpack
5. Fail
6. Kill yourself
7. Equip a backpack as normal

Expected behavior
I expect the backpack to be unequipable after sleeping in the sleeping bag until after a player death happens

Required informations (please complete the following information):

• Mod version: 1.19.2 - 8.2.10
• Mod Loader: Fabric

Could you record a video how does that happen, I cant reproduce it by any means

This same issue happened to me. Killing my player allowed me to equip the backpack on my back again.
I am on forge 1.19.2. Version 8.3.4 of the mod
I have a lot of mods installed, around 140-ish so it could be caused by any one of those mods

Edit: Strangely can't reproduce it after dying. If it happens again I will record it
