Disabling Mythic Metals does allow the game to run properly, but I want to use that mod still. What I have no idea about is how to make the game run properly WITH it enabled.

Have you tried updating the version of owo that is within your modpack? Update such mod to 0.9.3 version here: https://www.curseforge.com/minecraft/mc-mods/owo-lib/files/4152949

That worked. But now I have encountered a new problem. I can't join any worlds because it disconnects me, even though I am in single player! And since I already have this thread open and I have even less of a clue as to why this new bug is happening, why not reuse it?

latest.log

From reading you log it seems something bad is happening with Waystones. I suggest asking them for further support.

Given that this issue is no longer related to owo, I'll go ahead and close it
Cheers
