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.
