Error on user registration

When register new user I get this error:
{“success”:false,”data”:{“message”:[“Email already exists.”]}}
from page admin-ajax.php

Website page: https://farmaci.progettosalute.life/registrazione/

Installed plugin: User Registration – Custom Registration Form, Login And User Profile For WordPress (https://wpeverest.com/wordpress-plugins/user-registration/?utm_source=wporg&utm_medium=link&utm_campaign=ur-upgrade-to-pro)

Any ideas?

thanks
