1. Open the …/wp-content/plugins/the-events-calendar/src/Tribe/Integrations/WPML/Views/V2/Filters.php file.
2. Look for line 188.
3. Replace:

   $event->permalink = apply_filters( 'wpml_permalink', $event->permalink );
   

   With:

   // WPML Workaround for compsupp-6706
   $event_permalink = $event->permalink;
   
   if ( is_object($event_permalink) ) {
   	$event_permalink = (string)$event_permalink;
   }
   
   $event->permalink = apply_filters( 'wpml_permalink', $event_permalink  );
