Minecraft disconnecting me in a singleplayer world

[Juaum124]

I'm playing minecraft with a modpack I made myself, and for some reason, it's making my singleplayer worlds act as a multiplayer server. I randomly start lagging as if I have a bad connection to a server, and when I try to quit and save the world, I get stuck in an eternal "Saving World" screen, forcing me to close the game through Task Manager. All the articles I've seen online point to OptFine as the culprit, but I'm using embeddium instead. I even tried disabling it to see if it was the issue, but nothing changed.

I'm not sure what to provide for anyone trying to help me, so here are my logs and modlist.

Looks like the mod Chunky running some tasks causing these issues

Make a test without this mod

I removed the mod, but that doesn’t seem to be the issue. I created a new world, but the game still treats it like a server, even saying "Joining World" when I just created it.

Add the new log

The bug happened again. I broke an entire tree but didn’t get any blocks, as if I was lagged out. I then tried quitting the game, only to be stuck on the same infinite saving screen, forcing me to close the game through Task Manager.

Wasn’t it. I got the exact same problem. I went to cut down a tree, got 1 log, and the next 3 blocks didn’t drop anything. Also, the same "Saving World" problem happened again.
