I broke Nautilus; how to fix it?

reinstall nautilus or install a different file manager?

Hm...

Perhaps we could try right-clicking on a folder, clicking on "Open with
other application...", and then selecting Nautilus?

This will probably just work for the current user.

Respectfully, Adonay.
Have a nice day.
