Comment:

 Hi @alexpaterson, welcome to Trac! It sounds to me like something specific
 to your environment is trying to load this class twice. Could you share
 any more info about the callstack that is displayed when you see this
 error?

 In case it's helpful, this class used to be loaded in `wp-settings.php`,
 but was moved to `/wp-includes/meta.php` in WP 6.3 so it would be loaded
 earlier for environments that tried to invoke the class during
 sunrise.php. See https://core.trac.wordpress.org/ticket/58185#comment:8
 (and the resulting discussion).
