Error on Checkout

I’m not using wpml but polylang and since last update I can’t finish the checkout (I had to put something to allow it cause free woocommerce events are not yet working)
and I get
`[27-Jan-2022 20:43:25 UTC] PHP Fatal error: Uncaught Error: Call to a member function get_element_trid() on null in /home/xxxxxxxxxxxxxx/www/wp-content/plugins/wp-event-solution/core/wpml/init.php:43

I need to make it work again or do something with woocommerce and free checkouts
