    This error message…

    selenium.common.exceptions.SessionNotCreatedException: Message:  Could not start a new session. ... Response code 500.
.
Driver info: driver.version: unknown

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

    Your main issue is the incompatibility between the version of the binaries you are using as follows:

    • You are using chrome=98.0
    • Release Notes of ChromeDriver v98.0 clearly mentions the following :

    Supports Chrome version 98

    • But your chromedriver version is not getting detected.

    Driver info: driver.version: unknown

    So most possibly there is a mismatch between chromedriver version and the chrome=98.0

    Solution
