The quickest way around this loop is to clear your cookies/sessions, restart the browser, and login to Linkedin.
That should do the trick.
We're not exactly sure why causes the recaptcha loop. That said, we highly recommend readjusting Orca's automation hours down for a few weeks before ramping up the schedule.
You can do this under Automation Settings in Preferences, we recommend letting the bot rest on the weekends. More about Setting Automation schedule here.
Setting up an automation schedule won't guarantee that you won't get caught up in another recaptcha loop, but it will reduce the frequency of recaptchas.
