This error message...

selenium.common.exceptions.InvalidArgumentException: Message: invalid argument: user data directory is already in use, please specify a unique value for --user-data-dir argument, or don't use --user-data-dir

...implies that the --user-data-dir is already in use.

Your main issue is you have already an open Google Chrome browser session opened for your manual browsing.

There is no such error in your code block. However it seems you are executing program as an Administrator. But,

A common cause for Chrome to crash during startup is running Chrome as root user (administrator) on Linux. While it is possible to work around this issue by passing --no-sandbox flag when creating your WebDriver session, such a configuration is unsupported and highly discouraged. You need to configure your environment to run Chrome as a regular user instead.

Solution

Before you execute your test as an user e.g. Administrator, ensure that you don't have any open Chrome browser windows using the same user i.e. Administrator.
