...implies that the ChromeDriver was unable to initiate/spawn a new Browsing Context i.e. Chrome Browser session.

It seems the issue is with ChromeDriver,s security feature of Sandboxing. To bypass this feature you can use the argument:

--no-sandbox

So your effective code block will be:

• Java

  options.addArguments("--no-sandbox"); # Bypass OS security model
  

• Python

  options.add_argument('--no-sandbox') # Bypass OS security model
