Describe the bug
Attempting to equip the backpack via shift right-clicking it results in a crash and prevents the player from being able to rejoin the world (or server).

To Reproduce
Steps to reproduce the behavior:

1. Acquire a backpack of any kind
2. Place it on the ground
3. Shift Right-Click to try and equip it

Expected behavior
My game shouldn't have crashed and I should've been able to actually use the backpack.

Screenshots
Description and steps provided should be enough, no screenshots will be provided.

Required informations (please complete the following information):

• Mod version: 1.17.1-6.0.3
• Forge version: 1.17.1-37.0.71 (happens no matter the version)

Additional context
Context is not required, crashlog will be linked below.

This is what the launcher spits at me whenever I equip the backpack via the aforementioned method:

The game crashed whilst unexpected error
Error: java.util.NoSuchElementException: null
Exit Code: -1

By the way: Deleting the Traveler's backpack entry created in the player's NBT file doesn't work. Forge just creates a duplicate with the same entries as before >:(
Edit: Or it just fills in the blank you created which is pretty stupid since that means my main survival world is probably fucked :|

Hmm, that's strange one

I can't reproduce this issue
