Hello Dan Joshy,
Thank you for posting in Microsoft Q&A.
Based on your description, this appears to be related to Google's detection of unusual or automated traffic and the CAPTCHA challenges returned by Google Search. Since this behavior is controlled by Google's services rather than Windows, Microsoft does not have visibility into or control over how these detections are triggered.
Because the issue is occurring specifically with Google Search and its CAPTCHA system, I recommend contacting Google Support or seeking assistance through Google's support channels for further investigation.
Thank you for your understanding.
