1.19.2 custom modpack singleplayer world disconnects about 10sec in

[fmo]

I don't know what could be the issue, but I have been trying to create a fun modpack to hopefully start a server with for my friends and I. In order to do that I'd need to finish my modpack. However, I've been running into many issues while doing so and worked many of them away on my own. Not this time I'm afraid... Could you help me figure out the problem? I'm not sure what information is important so I'll just give the logfile (It's a lot).

Cracker's Witherstorm is conflicting with Greek Fantasy.

Cracker's Witherstorm seems to break things a lot apparently, and I don't mean the boss itself.

Thanks! It stopped disconnecting, but now it still crashes regularly

Could you figure out what could be causing the crash?

GaggleOfGolems is causing the problem.
