 * This error occurs even in the latest WordPress version when using PHP 8.1. The
   easiest solution would be to use PHP 8.0.
 * There is a ticket for this and other error messages related to PHP 8.1 with the
   developers: [https://core.trac.wordpress.org/ticket/54504](https://core.trac.wordpress.org/ticket/54504)
