Fix InvalidSessionIdException

✅ Solution

The "InvalidSessionIdException" in Selenium usually occurs when the browser session is prematurely closed or lost, often due to unexpected browser crashes, script errors terminating the driver instance, or network issues disrupting communication. To fix it, ensure your browser doesn't close before your script finishes by handling exceptions and gracefully closing the driver with `driver.quit()` in a `finally` block, and verify stable network connectivity during test execution. Finally, confirm your browser and driver versions are compatible to avoid driver instability.
