Expected Behavior

I am expecting the game to load as normal with the new mod I added.
Also expect keybind to show up in menu

Actual Behavior

The game continues to crash each time I load it since this mod has been added.
Keybind does not show in menu.

Steps to Reproduce

add the mod to game and load it, it will crash while loading, normally after going full screen or loading world.

Version of Minecraft, Carry On, Forge/Fabric

1.21.1 forge

same thing sorta happened to me,fabric. I plopped the mod in my mods folder,loaded up my world that I've had for over a year,and it corrupted the shit. I was able to get the items that were in my inventory back,but lost everything in the world. it was just default seed again. last time I use this mod.
