Hello, @mathieu Fontaine,
Thanks for using our theme and for contacting us.
Our developers working on compatibility with the latest woocommerce version.
You can downgrade WC version – https://prnt.sc/9zDbDPn58IxX https://wordpress.org/plugins/woocommerce/advanced/ or wait for the next theme update, it will be released soon.
Next time, do not update WC before the theme update, here is our changelog – https://xstore.8theme.com/update-history/ with info about compatibility.
Regards 8Themes Team.
