Hello,
Thanks for using our theme.
In the text of the error, you can see that it comes from the WooCommerce plugin, so you need to contact their support.
I’ve found this topic – https://wordpress.org/support/topic/error-after-updating-to-new-version-2/ on WC support forum, it seems the error comes from the latest WC update.
Further consultation should be provided by WooCommerce team.
Regards
