Answer 1

I have the same issue as you, so I tried to run it as root

sudo nautilus .

But there were still warnings, so I found solution here.

So finally I ran

sudo killall nautilus
sudo apt-get purge nautilus
sudo apt-get update
sudo apt-get install nautilus 

Or one line solution

sudo killall nautilus && sudo apt-get purge nautilus && sudo apt-get update && sudo apt-get install nautilus
