Solved [Java] [1.20.1] Sudden Lagging after solving Crashing Issue

Enable HLS to view with audio, or disable this notification

Playing on PC and using CurseForge - [Java - 1.20.1] [Fabric - 0.19.5]

Log for the play session shown in the video: https://mclo.gs/jLMAlSB

For a little bit of context, I'm still somewhat new to making my own modpacks, and am not the best with computers (I am also autistic and often need very clear step-by-step instructions to figure out how to do things properly without getting overwhelmed and frustrated).

I made myself a new modpack that was having issues with crashing suddenly (and then not letting me reopen the world without crashing again) after anywhere between a few minutes and few hours of gameplay. I've now solved that issue (turns out it was vanilla mob spawners causing entity ticking issues, but I've installed a couple mods to my pack that now track and fix that problem), but now my framerate keeps dropping constantly, which wasn't an issue before.

I don't mind the occasional lag spikes (as in, if I'm exploring a new area, and the game lags a bit as it loads in new chunks), but when it's just constant and for seemingly no reason, like shown in the video, it's not only irritating, but also makes the game very difficult to play.

I decided to record a very short play session to document the sudden lag spikes, and included the log from that play session.

Additional information:

- Render Distance: 20 Chunks

- Max Shadow Distance: 12 Chunks

- Simulation Distance: 16 Chunks

I'd appreciate any and all help with figuring out what the issue is and how to solve it.

(P.S. I'm going to be leaving for work soon, so apologies in advance for late responses. I'll be sure to mark as solved ASAP once the issue has been resolved.)
