Steps to reproduce the problem:
1. Double click the icon. It animates to open but never appears in the dock.
2. Attempting to open from terminal using open /Applications/Google\ Chrome.app/ returns quickly with the message shown.
3. Experience a hard crash / hard reset, then disk verify and repair.
4. Also experience loss of the keychain so I now need to enter passwords for: ssh, network servers, google backup etc, anything that uses macOS secure password storage i guess. i think my machine has hardware issue. is well used laptop about to have OS re-installed due to..... something is causing it to use virtual memory / swap but it has 16 GB ram.
