Additional Information

Hi, I'm reporting this rare issue I'm having only when Lithium is installed. It's happening in Minecraft 1.18.1 / Fabric 0.12.12 and it was also happening in Minecraft 1.18 / Fabric 0.12.8. It's probably because another mod, but I can't tell what is the cause of it. Thanks.

I can actually confirm this. I thought it was just a fluke, although I also got the issue in singleplayer where I got kicked to the server list screen. Without any errors, was even debugging at the time.
I was only running Lithium & Carpet

Temporary workaround until the next release:
Add mixin.entity.inactive_navigations=false to the LithiumConfig
