v2.7.2 thows TypeError with PHP 8.1

I just applied the update released a few minutes ago and since them face fatal errors on several actions, like viewing the user list or deleting comments:

Jan 13 10:43:34 domain.com php[2558815]: PHP Fatal error:  Uncaught TypeError: call_user_func_array(): Argument #1 ($callback) must be a valid callback, class W3TC\Util_AttachToActions does not have a method "on_comment_status" in /var/www/blog/wp-includes/class-wp-hook.php:308

Bad is that even downgrading to v2.7.1 does not solve the issue (I assured all caches were cleared). Probably some database change is responsible?

I use PHP v8.1.12 and MariaDB v10.6.11.
