mts version: 1.16.5 - 22.12.1 (newest)

When you add Immersive Vehicles and any addon pack to the game, place any vehicle and start the engine, your latest.log will be stuffed with [Sound engine/INFO]: [net.minecraft.client.audio.Listener:handler$zzc000$inject_setListenerOrientation:533]: SETTING; And
it will start to freeze the game gradually.
I dont think this log would be useful ...
latest.log
And here is the config file
mtsconfig.json

Addressed in 22.14.0.

I'm leaving this open until said update drops, since it affects current users.

Issue found, fixed, and will be in next update.
