This is usually caused by a mismatch in versions between Chrome (the browser) and Chrome WebDriver.

Try updating them: Tools > Update WebDrivers

hi Thomas,

thanks for the help, i tried this multiple times but didn’t work even i changed ChromeDriver Manually also but its as ease.

@gunjan_mishra

Just let Chrome updates completely, restart your machine then try running again.

Thanks

no use i tried this also…

Yeah, like “Turn it off and turn it on again… no, off again and then on again…”
