Oracle APEX: Problem after restoring backup

I deleted my app and restored it using "Manage backups" option. Everything was fine but now I get error when loading HTML page items.

On login page I get this message:

I am using Oracle Cloud Autonomous Database environment, is it possible to update those files manually or do I need to contact Oracle Support, maybe any other solution?

Thank you.

begin 
        apex_instance_admin.set_parameter(
            p_parameter => 'IMAGE_PREFIX',
            p_value     => 'https://static.oracle.com/cdn/apex/24.1.7/' );
        
        commit;
  end;

Used this and configured in Admin Services under Manage Instance
