...implies that the file com/google/common/collect/ImmutableMap might be corrupted or there is some incompatibility between the version of the binaries you are using.

Further you need to take care of a couple of things as follows:

• Instead of storing the chromedriver.exe binary right under C:\ try to put it within a directory as C:\\BrowserDrivers\\chromedriver.exe and change the System.setProperty() line accordingly. So effectively, the line of code will be:

  System.setProperty("webdriver.gecko.driver","C:\\BrowserDrivers\\chromedriver.exe");
  

Also ensure that:

• JDK is upgraded to current levels JDK 8u311.
• Selenium is upgraded to current released Version 4.1.3.
• ChromeDriver is updated to current ChromeDriver v100.0 level.
• Chrome Browser is updated to current chrome=100.0 (as per chromedriver=100.0.4896.60 release notes).
