Unable to load AngularJS pages, e.g., CiviVolunteer and CiviCRM status page
It looks like you have a config mismatch between your CMS and your CRM. The tell is in the CORS error in the screenshot you provided. It looks like your site is serving content at https://www.example.org while CiviCRM has specified a base URL of https://example.org. (Note that one URL includes the "www" subdomain while the other does not.)

These URLs have to match,or you need to configure your server to allow cross-origin resource sharing (CORS).

I would recommend the easiest solution, which is to ensure that CiviCRM serves assets via the same base URL as your CMS. In civicrm.settings.php file:

define('CIVICRM_UF_BASEURL', 'https://www.example.org/');
