Hi there,
Thanks for getting back to us.
I just checked WooCommerce with PHP 8.1, and I can see it’s working fine for me.
Seems like this issue is coming from some third-party plugin or a theme you are using on the site.
Can you please try to deactivate all the plugins and keep only WooCommerce activated with the Storefront [theme](https://pcm.www.ads-software.com/themes/storefront/)?
Let me know if you are still able to replicate the issue.
Best,
