acf frontend 2.8.14 breaks site

When I updated to acf frontend 2.8.14 and try to open an elementor page I get the following. Any suggestion would be gratefully appreciated.

Fatal error: Uncaught Error: Class 'ACFFrontend\Module\Widgets\Duplicate_Post_Widget' not found
in /home3/kmuznet/public_html/kmuzlive/wp-content/plugins/acf-frontend-form-element/includes/elementor/module.php on line 63
