Mod Loader: Fabric 0.16.10
Mod Version: 9.1.22
Game Version: 1.20.1
(edit) Launcher: Prism 9.2

1. Describe the bug
   when manually throwing away an item from the backpack inventory, by clicking the item, and moving it out of the GUI to throw it, my game stops responding and crashes

2. Write steps to reproduce the bug
   open backpack inventory, grab item from inventory (doesn't seem to matter what item) hover item outside of GUI, click to throw the item (Do not use "ctrl+q", as the bug will not be reproduced, and this function will work properly without crashing the game)

3. What is expected behavior
   Game will either close on its own after freezing up for a short time, or game will freeze and stop responding (seen in SS below)

4. Screenshots (If applicable)

bug also seems to not occur if the item is in the player inventory, it must be in the backpack inventory, or the bug will not be reproduced

Can you share the crash log?
