Hi! After running nautilus from the command line, I received a log showing what is happening in my case. The problem is generated by the gphoto2 services.
To fix it, I removed the service. After that, the Nautilus and Gnome applications that depend on file system services returned to work fine again. I have opened a issue in gphoto2 repositoy on Github for investigation and fix.
