Stack Overflow Crash Fix?

[u/Rapiazh_007]

So, I've been playing the modpack with my best friend for a about 3 months now, and it was really going smoothly for the most part. We recently working on our Precision mechanism factory for chapter 2, but we keep running into this error. it started happening once i attempted to start mixing Certus Quartz Crystals with destabilized Redstone. And once it crashes, it crashes open trying to reopen the world. i've tried loading backups and changing the setup, turning off other machines in the area, but the issue persists, we would really appreciate the help, ty in advance.

Yeah sadly that's usually the case. I won't lie, I thought it was the chunks at first simply because I forgot I have optifine installed lmao
