0. ALWAYS PROVIDE INFORMATION ABOUT MODLOADER (Fabric / Forge) AND MOD VERSION (For Example 1.19.2-8.2.10)
   Fabric 1.21.1
   Accessories 1.1.0-beta4
   Trinkets Compat Layer 3.10.0-beta 14
   Traveler's Backpack 10.1.2

1. Describe the bug

Game crashes when equipping backpack in Back slot. Cannot rejoin server without reset. I posted this in the Git for Accessories too because tbh I can't figure out which mod is doing the crashing primarily as other features of both work fine.

2. Write steps to reproduce the bug
   Obtain backpack
   Attempt to put backpack into Back slot (Trinket/Accessories menu of inventory)

3. What is expected behaviour

Apologies in advance if this is not the proper avenue for posting this bug!

Hey @Tiviacz1337 why are you checking for an accessory menu class instance by chance? The Latest screen rewrite refactors such but you can use AccessoriesMenuBase as the instance check.

Hello, I check it because it was causing duplication issues when tick method was running during player accessory swap in the gui and that was the only solution Ive came up with

Hi,
Just wondering if this issue will be fixed?
The backpack does wok in previous versions of accessories but not in the latest version which added some good features.
