Thanks for sending that over. That looks correct to me – the Secret Agent helper application is running and doesn’t have a non-zero exit code (indicating it launched properly). That leads me to believe something may have gone awry with your System Privacy settings for Codebook (Accessibility & Automation).
Would you try this suggestion to see if un-checking and re-checking the Privacy settings here help: Troubleshooting Codebook Secret Agent
If you can’t uncheck and re-check the Privacy setting in Accessibility after hitting the unlock button and authenticating in the lower left hand corner, would you try removing Codebook from the Accessibility privacy setting by selecting Codebook from the list, clicking the - button, then clicking the + button and selecting Codebook in the Application directory to re-add it.
Let me know the results.
