Captcha is not responding to any input

UPDATE 06/02/2023
Issue reoccurring.

UPDATE
Brave Search is working again. No configuration changes made to my end; event is apparently self-healing.

Description of the issue: Navigating to search.brave.com prompts new Proof of Work captcha to load. Clicking “I am not a robot” button displays progress bar briefly, but no change in page.

Have attempted multiple times; no change in page.

Have attempted to use traditional captcha through indicated link: No change in page.

Have attempted with and without VPN active: The result is the same regardless of VPN status.

Have attempted with Brave browser Shields up and down: The result is the same regardless of Shield status.

Have attempted in Private browsing: Initial page will load. Attempting a query prompts the captcha to load, and the above behavior resumes.

Have attempted in other browsers: Initial page will load. Attempting a query prompts the captcha to load, and the above behavior resumes.

Based on observations, the issue appears to be related to cached data and was not a problem prior to today.

Brave Version (check About Brave): 1.51.118
