Same here. Lost count of how many times this has happened now on two separate macbook pros. Just happened again today. I click on it and then it disappears from the toolbar. I go into manage my Chrome extensions and it says it's corrupted. I've tried repair and uninstall and reinstall. It's bloody annoying, especially as company policy is 2 factor login. This time was worse as I recently got a new phone and had a long process to get Google authenticator on my new phone, having to report having lost my device with Google Authenticator. Because of the corrupted extension, I couldn't login to set it up on my new phone. This really needs to be fixed. It's appalling. As we are a small 2 person team, a move to another provider wouldn't be too bad, although not convenient either. No issue on firefox.
