Not able to launch chrome 117

I was using chrome browser Version 117.0.5938.150 and Selenium Version: 4.12.0. but the “Open Browser” keyword has failed with the error,

NoSuchDriverException: Message: Unable to obtain driver for chrome using Selenium Manager.

and is failing to launch the browser instance. This was working a couple of days ago. any help/workaround here would be greatly appreciated as i am unable to find a driver executable for chrome version 117

Selenium is trying to download the chromedriver for that version and it failed.
You need to do that management on your own. Just go to chrome-for-testing site and download the correct version and O.S package, and extract to a directory listed in $PATH/%PATH% or /etc/paths (Linux, Windows and macOS).
