Answers.Text: I tried this fix, but it deleted all the custom templates I had created. It seems like this is only a fix if you haven't made any tweaks to Mosaico.

Body: <p>I am running CiviCRM version 5.43.0 on Wordpress 5.8.2 with PHP 7.4 - it's a new site, freshly installed.</p>
  <p>We had Mosaico running (though in fact at the time I think we didn't have either GD or php-ImageMagick installed!) via the CiviCRM Extensions manager. FLexmailer, GD and php-ImageMagick are all now installed (for both PHP 8, and for 7.4).</p>
  <p>On upgrade to 2.8, Mosaico is now generating errors.  When opening CiviCRM, a modal appears:</p>
  <blockquote>
  <p>Mosaico: Packages are missing Mosaico requires dependencies in its
  &quot;packages&quot; folder. Please consult the README.md for current
  installation instructions.</p>
  </blockquote>
  <p>And if you go to Mailing &gt; New Mailing a message appears:</p>
  <blockquote>
  <p>Mosaico cannot be displayed because this system does not meet all requirements.</p>
  </blockquote>
  <p>I have the CiviCRM log viewer extension installed, and this is not showing any errors.  Google searches don't return anything obvious.  I'd appreciate any assistance in debugging this error further - should I be asking this on Mosaico's boards instead? Many thanks!</p>
  <p>Tried so far:</p>
  <ul>
  <li>Install phpImageMagick</li>

  <li>Clear CiviCRM Caches</li>
  <li>Server reboot (never hurts hey)</li>

  I have the CiviCRM log viewer extension installed, and this is not showing any errors. Google searches don't return anything obvious. I'd appreciate any assistance in debugging this error further - should I be asking this on Mosaico's boards instead? Many thanks!
