Chrome is currently on v91 and it needs a driver to match. Install Chrome in its default location and make sure it is updated. Then get the latest Chromedriver. There's a NuGet package for chromedriver if you prefer to manage it that way.

    @NarendraC note he said Chrome is on v91, not v90, which you've mentioned...

  • Matched chrome & driver version. Installed chrome in its default location @kirbycope as suggested.Still observed errors. Small fine tuning resolve issue. Catch was - I uninstalled my Chrome browser manually and install it again. Voila :) Everything started working as expected.
