OK so when I tried to customize plugin I got an error:

That got me thinking about my network configuration. I have an app called Lockdown running, that is a tracker-blocking VPN configuration. When I disabled it and restarted calibre, the Goodreads Sync plugin began working again. Sorry for the trouble.
