Forge 1.20.1, Quark crashes when starting/restarting multiplayer server

[muppetenergy]

I don't have much info to give other than the crash report. This has been happening sporadically, more recently I've had to kill the server when it hangs on trying to close it.
It also will often not create a crash log since it gets stuck trying to shut off.
Here are 2 of them though from the past couple days:
