While I do have over 300 mods, Ive narrowed down the issue being something to do with Kambrik. I have no idea how to read crash reports fully yet, and need help breaking down where the problem is, and how I could fix it. I am realtively new to modding, so treating me like Im dumb is fine.

Crash report:
A mod crashed on startup!

Crash log:
latest.log

Nevermind, I found a new problem when screwing with it. Im going to move to a different repo

This is because Kambrik has a prelaunch stage and thus Kambrik's prelaunch startup is interrupted by another mod's mixin failure. It looks like whatever mod isassociated with the package ca.fxco.memoryleakfix is failing to inject a mixin.
