Try to replace the line #91 in the file inc/integrations/woocommerce/modules/wishlist/class-ui.php with this one

if ( woodmart_get_opt( 'wishlist_expanded' ) && class_exists( 'XTS\WC_Wishlist\Wishlists_Group' ) && is_user_logged_in() && $this->is_editable() && empty( $_GET['opauth'] ) ) { //phpcs:ignore

Kind Regards
