I’m sorry to see this error when using blueprints. Could you tell me some more details on the environment you are using for this site and the original site you created the blueprint from? Have you tried restarting the newly created site? Another suggestion would be to try and restart the Local Machine (navigate to Help, then select “Restart Local Machine”).
If none of that helps you there, could you post the Local logs and the site log files? How do I retrieve Local's log file?
