Answers.Text: I had this exact same problem. I just removed enshrined/svg-sanitize from the composer.json file. This then gave an error for Twig when I tried to update, so I removed that from composer.json too. The update then worked. Not sure what the implications of doing this are, if any.

Body: <p>Here's what I'm getting:</p>
  
  <pre><code>Error: An error occurred
  
  Output: Loading composer repositories with package information
  Updating dependencies
  Your requirements could not be resolved to an installable set of packages.
  
    Problem 1
      - Installation request for craftcms/cms 3.0.18 -&gt; satisfiable by craftcms/cms[3.0.18].
      - craftcms/cms 3.0.18 requires enshrined/svg-sanitize ~0.9.0 -&gt; satisfiable by enshrined/svg-sanitize[0.9.0] but these conflict with your requirements or minimum-stability.
    Problem 2
      - craftcms/cms 3.0.18 requires enshrined/svg-sanitize ~0.9.0 -&gt; satisfiable by enshrined/svg-sanitize[0.9.0] but these conflict with your requirements or minimum-stability.
      - pierrestoffe/craft-language-redirector 1.0.2 requires craftcms/cms ^3.0.0-RC1 -&gt; satisfiable by craftcms/cms[3.0.18].
      - Installation request for pierrestoffe/craft-language-redirector 1.0.2 -&gt; satisfiable by pierrestoffe/craft-language-redirector[1.0.2].
  
  Running update with --no-dev does not mean require-dev is ignored, it just means the packages will not be installed. If dev requirements are blocking the update you have to resolve those problems.
  </code></pre>
  
  <p>I've attempted:</p>
  
  <ul>
  <li>removing <code>vendors</code> directory</li>
  <li>removing <code>composer.lock</code> file</li>
  <li>updating via CLI</li>
  <li>changing craftcms to <code>3.0.18</code> and running install</li>
  </ul>
  
  <p>Anything else I can try?</p>
