Shift Key is toggling crouching in specific Minecraft Versions in Omarchy 4

[slyd0x]

Hi,

if I try to play an older Minecraft version like 1.7.10 or 1.12.2 as soon as I hit the left shift key, it is toggled so I am always crouching ingame. This happens in vanilla Minecraft as well as modpacks.
It seems like there is maybe a conflicting keybind on Minecraft and Omarchy 4, but I could not find it yet.

Strangely though, this does neither happen on newer Minecraft versions like 1.26 nor was it an issue on Omarchy 3.
