WP_MS_Sites_List_Table not found (MultiSite)

Hi,
unfortunately I get another error when I try to assign the profile. Here is the extract from the Errog log:

Uncaught Error: Class "WP_MS_Sites_List_Table" not found in /var/www/html/wp-content/plugins/next-active-directory-integration/src/shared/WordPress/Multisite/Ui/Table/ProfileAssignment.php:14

Can you take a look at it?

Many thanks and best regards
