title: Call to undefined method GuzzleHttp\Utils::chooseHandler() when sending email
body: <p>My application was working fine and when I woke up today i faced this error:</p>
  <blockquote>
  <p>Call to undefined method GuzzleHttp\Utils::chooseHandler(</p>
  </blockquote>
  <pre><code>/opt/bitnami/apache/htdocs/php/plain/vendor/guzzlehttp/guzzle/src/HandlerStack.php:42
  
  function choose_handler(): callable
      
      {
      
          return Utils::chooseHandler();
      
      }
  </code></pre>
  <p>This is when the error happens:</p>
  <pre><code>Mail::to($request-&gt;email)-&gt;send(new ProfessionalInvited($clinic, $person, $inviteId));
  </code></pre>
  <p>What could happened? And what should I do? I already tried deleting my vendor and composer.lock and reinstall everything. But without success. I was also having this error in API calls using guzzle and when I changed to cURL everything worked fine. But I dont think I can do the same to send emails since Guzzle is a dependency.</p>
