Body: <p>Just did a clean install of Joomla 4.23 with Civi 5.54.0 running on PhP 8.0 via xampp. Install went fine including databasee upgrade but can't get to CiviCRM dashboard. Error message is
  'Class &quot;IntlDateFormatter&quot; not found&quot; and button sends me back to Joomla dashboard.
  My understanding is that Joomla 4.x works with Civi 5.54 and both are compatible with PhP 8.0. Am I missing a compatibility issue? What else could it be?
  Thanks,
  Kate</p>
