Google Slides embed stopped working

[edu-shamilton1]

Something seems to have gone wrong.
Currently getting an error when looking for the extension and it has disappeared as an installed plugin in Slides and disappeared from the marketplace.

400. That’s an error.

The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

Same for Docs, entire draw.io / diagrams.net plugin for Google Docs, Slides seems to have gone.
