    I get this error, i solved it with a simple validation in line 132 of cuwp.php in your plugin

    Change:
    wp_set_password(sanitize_text_field($_REQUEST[‘cuwp_pass1’]), $user->ID);
    To: if($_REQUEST[‘cuwp_pass1’])wp_set_password(sanitize_text_field($_REQUEST[‘cuwp_pass1’]), $user->ID);

    This happens when creating user with checkbox disabled and empty passwords (being superadmin )
