Fix UnpackAndThrowOnError

in Selenium

Solution

The "UnpackAndThrowOnError" error in Selenium often indicates a conflict accessing the Chrome user data directory, usually because another Chrome instance (or a previous Selenium session) is still using it. To resolve this, ensure all Chrome processes are closed before starting a new Selenium session. You can achieve this by either explicitly killing Chrome processes in your code before initializing the driver or using a unique user data directory for each Selenium session.
