(1.18.2) Crashes after loading

[u-ares]

I've been making a modpack, so it's hard to tell where it really crashed. But it has definitely started crashing when installing this mod, and stopped crashing when disabling the mod.

When loading, the mod that changes the loading screen doesn't work, causing the vanilla Mojang loading screen (obvious sign of a incoming crash) and suddenly closes itself. It does create a crash log, though.

Here's the crash log: https://pastebin.com/0476e58c
