According to this Cisco Collaboration Help article last updated on Jun 11, 2018:

Announcing the retirement of the Webex App for Chrome

It also lists limitations for using the Chrome extension:

  • Limited to attendees only. Hosts must use the Webex Web App or the desktop app.
  • Attendees can only join Cisco Webex Meetings on sites running WBS30 or higher.
  • Does not support the Cisco Webex Meetings product meetings.webex.com.
  • Attendees cannot join meetings with end-to-end encryption enabled.
  • Attendees cannot join meetings on the "VoIP-only" site type.
  • Does not support content sharing

So it's likely that it just doesn't work anymore. The article referenced in the announcement suggests that you now can use a HTML5 based solution that doesn't require any extensions anymore.
