Fix InvalidOperationException

in Selenium

Solution

InvalidOperationException in Selenium often arises from mismatched browser driver versions (e.g., ChromeDriver) and the browser itself (e.g., Chrome). Ensure your browser driver's version aligns with your installed browser version. Download the correct driver version and specify its location when initializing your WebDriver.
