The script stopped,the log is :Thread #1 : Waiting for element >CSS> #username_LpX77.
May be the cause of incomplete page load, how to ignore this case?
Finally I ended using (it's also working for different languages of Recaptcha challenges) if someone searches for the same:
">CSS>iframe[src^=' https://www.google.com/recaptcha/api2/bframe ']>FRAME> >CSS>#recaptcha-verify-button"
