Oli for some reason doing that seems to have massively sped up how fast my local version loads both in CP and website - not sure why but thanks!

<p>I have installed and used the Contact Form Extensions plugin a few times but this time it's not working. I can see it in the CP but when I click to install it throws the error:</p>

<blockquote>
  <p>Invalid plugin – craft\errors\InvalidPluginException
  'No plugin exists with the handle "contact-form-extensions".' </p>
</blockquote>

<p>When I install it the command line does say something about Carbon 1 being deprecated but not sure if it's related?</p>

<plugins>
No plugin exists with the handle "contact-form-extensions"
# No plugin exists with the handle "contact-form-extensions"

When I install it the command line does say something about Carbon 1 being deprecated but not sure if it's related?
