Checking the manual for my X100F, it says when FOCUS ERROR is displayed it means "Camera malfunction. Turn the camera off and then on again. If the message persists, contact a FujiFilm dealer"
I realize this is an earlier version of your X100V, and it's probably not what you want to hear. Nonetheless, it's from FujiFilm's manual.
Hope it's not too serious a problem.
I have a X100T, they are probably all similar.
