title: Opis\Closure\SerializableClosure - Error afer PHP 8.1 Update
body: <p>I have updated my system to <strong>PHP 8.1</strong> (XAMPP).
  Now I have the problem that when I enter the command &quot;<strong>php artisan serve</strong>&quot; I get the following error message:</p>
  <pre><code>Opis\Closure\SerializableClosure implements the Serializable interface, which is deprecated.
   Implement __serialize() and __unserialize() instead 
  (or in addition, if support for old PHP versions is necessary).
  </code></pre>
  <p>Can you help me what I can do to make it work again?</p>
