Release notes:
https://github.com/kiwidude68/calibr..._pages-v1.12.1
Indeed Goodreads fully transitioned over to their new book page design for the website, this particular feature would have been broken (or at best intermittently working) for a while now.
@Waylander - curious about the FictionDB error in your startup debug log there. By chance have you not updated the plugin for a long time? I would suggest uninstalling it, not doing you any good in it's current state, just slowing your calibre startup
