 * Please use in your wp-config.php for live pages:
 * `define('WP_DEBUG', false);`
 * Do you have a deleted category which is selected by Category Archives Block? 
   Please delete it manualy.
 * We use also PHP 8.1 and couldn’t find any issue.
 * Can you give us all your option settings, may as screenshot?
