You can download corresponding ChromeDriver at https://sites.google.com/a/chromium.org/chromedriver/downloads
FYI, webdrivers are located at "C:\Users\Public\LogiGear\TestArchitect\Automation\webdriver_server" as it already shows in your screenshot.
Thanks @Hien
I downloaded ChromeDriver v90.0 and configured the Automation Agent to point to that location and it worked.

Need to update TestArchitect v9.0 Automation Agent for Google Chrome as it shows version 90.0 but actually contains version 86.0
Screenshots attached.
