If you're running into the "SessionNotCreatedException: user data directory is already in use" error with Selenium Edge, try setting up a fresh, temporary user data directory for each session or just leave out the --user-data-dir argument altogether. Running Edge in headless or incognito mode can also help prevent profile conflicts. Make sure you always close the driver properly with driver.quit() after saving your table. If you're using Great-Tables, it's a good idea to pass in a custom Selenium driver that's set up this way. And don’t forget to double check that your Edge, EdgeDriver, and Selenium versions all match up.
