hi @zeus200003 Make sure your pom.xml file specifies 22</java.version> to ensure compatibility with Java 22. Also, correct the usage of driver.get() in your Selenium script by including the full URL with the protocol e.g., driver.get("http://www.google.com");. These steps should resolve the issues you're encountering with Selenium not starting and ensure proper navigation in your WebDriver script.
