Hi @anand1,
Could you please check whether the chrome application got updated. Because the interface is different from the older version and UiPath might not be able to read the data using the selector.

Hi @vvaidya,
Recently chrome browser has been updated and due to which UiPath is not able to communicate with the browser.
Could you suggest a way how to handle these in the future.
