Hi,
The issue is, that your site is accessed through the WWW subdomain and there is a CORS policy on your server preventing assets from loading from the non WWW version. WordPress is configured on the non-WWW version, but your site still can be access via the WWW. If I visit the site URL without the www. domain prefix, it all works perfectly: https://i.imgur.com/RNgIn4s.png
The errors you are seeing are reported by the server, which is not able to load some other assets either. The solution should be very simple, just redirect all requests from the www. subdomain to the non-www version. You should be able to find a few tutorials on google on how to do that safely.
