I gave you the solution ??
Hopefully it will be fix in 1.4.7

Do you plan a release with the fix ?

Here is my hack to fix this. You should now what you do before using this.

add_action(
    'pre_acui_import_single_user',
    'checkUserInBddBeforeInserting',
    10,
    2
);



function checkUserInBddBeforeInserting($headers, $data): void
{
$keys = array_keys($headers, 'id');
if (count($keys) === 1) {
    $userId = $data[$keys[0]];

    if (get_userdata($userId) === false) {
         global $wpdb;

         $keys = array_keys($headers, 'user_login');
         $userName = $data[$keys[0]];

         $wpdb->insert(
             $wpdb->users,
             [
                 'ID' => $userId,
                 'user_login' => $userName,
                 'user_nicename' => $userName, // Necessary to avoid some warning about cache
             ]
         );
    }
}
}
