Please attach a jstack output when the game is stuck.

Run jstack -l pid in a cmd, where the pid is the PID value of the game process in the task manager, and paste the entire output of the command in a paste site like mclo.gs.

Immersive Engineering is triggering an awful sync load on lighting thread that deadlocked the server. They should be using a safer approach like AuxiliaryLightManager: neoforged/NeoForge#464 , or something else.

This should also be reported to Immersive Engineering.
