Error when adding products to cart

Hello,

We are suddenly facing an issue using WooGift extension in the website of one of our clients, a fatal error appears when we add a product to the cart.
Here is the wp_debug trace :

Fatal error: Uncaught ArgumentCountError: Too few arguments to function FGW_gift_cart_item_price_custom_label(),
1 passed in /var/www/vhosts/flex-on.fr/httpdocs/wp-includes/class-wp-hook.php on line 308
and exactly 3 expected in /var/www/vhosts/flex-on.fr/httpdocs/wp-content/plugins/free-gifts-product-for-woocommerce/main/frontend/free-gifts-frontend-function.php:39

We already used and retested recently the extension and it was working well, our client needed to create a new gift product and then configured the plugin to do so, since when the error appears for any product that we add to the cart. I tried different combinations of settings and products but the problem is still there.

Do you have an idea of what could cause this ArgumentCountError ?

Thank you for your time,
Regards
