iChunUtil-1.16.5-10.5.1.jar vs Better End Sky (Forge) EndSky-1.2.jar Critical Error whilst initiating

[GentlemanGnu]

Was requested to add Hats and Googly Eyes to my latest modpack. Upon doing so, I kept getting "Error, Game Crashed". Snce there are 130 mods in my pack, I have narrowed it down for you. I don't know which one is not playing nicely.

the essentials... Forge 1.16.5-36.2.22.jar java 1.8.0_51, Oracle Corporation

Mod List: iChunUtil-1.16.5-10.5.1.jar |10.5.1 EndSky-1.2.jar Better End Sky 1.2

The game crashes whilst initiating. Crash repeatable with just these 2 mods included. I'm using the Curseforge Launcher, if that helps at all.

full crash report available on request.

As we discussed privately on Discord, the issue is on the Better End Sky end. Closing.
