I am getting the same errors. This is happening after either the latest YOAST update and/or the latest Default Editor / Gluttenburg Updates.
Dashboard is showing a spinning yoast logo under “Yoast SEO Post Overview”
Pages & posts are showing the “Yoast SEO Premium” box but said box is empty. This is a yoast absolute break. Nothing else is causing this – just yoast.
FIXED.
If you have the classic editor and Gutenberg activated, it will break the YOAST metaboxes. Go into your PLUGINS > Gutenberg > Deactivate
Everything will then return to normal.
For those others reading this – DO NOT USE GUTENBERG until it is 100% in production. There are still a lot of compatibility issues with Gutenberg and other prominent plugins.
IMO – Gutenberg is crap anyways!
Thank you so much! So helpful!!
Thanks for the Gutenberg hint. I find Gutenberg awful anyway in it’s current state so it is easy to deactivate it.
Edit: Works!

We thank you for bringing this issue to our attention. We apologize for the trouble you are experiencing with the plugin’s latest release. A bug report has been sent to our development regarding plugin conflict occurring when the Classic Editor plugin and Gutenberg are activated. Disabling Gutenberg is an alternative for now.
You can view the report here: https://github.com/Yoast/wordpress-seo/issues/11423
You may comment on the report so you may be kept aware of the updates/status of the issue.
closing this thread. Fixed on the recently released Yoast SEO 9.0.3.
