How to open a mounted partition?

Question

Debian

The section in caja stopped opening. The partition is mounted, but when I try to view the content, it says "Failed to show "/media/user/UUID". The address is not a folder." If you enter "/media/user/UUID" in the address bar, the result is the same. From the console, the section is viewed without problems. They write on the network that removing exo-utils helps, but I don’t have this package. How to be?
