Infinite load error when starting with KubeJS for Fabric installed.

Error: Start CurseForge 1.18 modpack for Fabric, Load. bug out and reload everything causing an infinite load loop.

Minecraft version: 1.18
Fabric Version: 0.12.8
Mod Version: kubejs-fabric-1800.4.0-build.235.jar

Modlist: https://pastebin.com/jmU2PDiA (does not contain KubeJS)

Same problem (but custom modpack with KubeJS). Infinite Mojang logo loop.

This one loops over and over: https://pastebin.com/PBiPLjtP

I have to stress out this problem, as it makes KubeJS unusable for 1.18.1.

I'm unfortunately suspecting that this is somehow caused by Inspecio, and thus cannot easily be fixed on our end (admittedly though it's also late at night so I'll probably take a look at a proper fix tomorrow). Can you see whether the issue persists without it?

Removing Inspecio did indeed fixed the problem and KubeJS started to work.

What the hell? I'm taking a look at this and I'm so confused as to how inspecio's causing this.

It's because of the KubeJS hook on TagLoader, it looks. Here's the crashing line, This is necessary and unavoidable so that tags can be used client-side. If you put in a null-check for the script manager, it won't cause this crash.
