Quick summary

The public block has missing informations (frontend):

Weirdly in edit mode, it works fine (backend):

...but block config options are missing (backend):

...and in the browser console I’m encountering this error (backend):
GET https://fedimedia.it/wp-json/wp/v2/users/0/?context=activitypub&_locale=user 404 (Not Found)
{"code":"rest_user_invalid_id","message":"ID utente non valido.","data":{"status":404}}

Steps to reproduce

1. Put the Follow me on the Fediverse block in a page/post
2. Open your browser’s developer console
3. Observe a 404 error from a REST API call to /wp-json/wp/v2/users/0/
4. Publish and check the frontend view
5. Notice that the block may appear empty or incomplete due to this failed request
