nautilus frozen, is there a proper solution?

nautilus is frozen, because of sshfs, a very common issue. Now I cannot kill/restart nautilus. I know there are issues with sshfs but at any moment am I not allowed to hard restart my own software which is nautilus in this case? I tried every pseudo solution available on the web:

1. killall nautilus or nautilus -q or killall -9 nautilus, with sudo
2. ps -aux | grep nautilus and then sudo kill <process_id>

I am using ubuntu 22.04.

This is age old question and I am struggling with this for more than a decade. The funny thing is that after sometime (a few hours) things get automatically solved. Or, I must reboot the whole system?Can anyone please explain why can't I force restart anything I wish?Please answer only when you know your solution works.

P.S. Sometimes killing sshfs helps, sometimes doesn't. It feels like not everything is in my hands, and luck plays most important role, even in 2024.
