Which version of Selenium WebDriver are you using? I suggest you to use the latest version 4.0.0-alpha05 and use the code below:

EdgeOptions edgeOptions = new EdgeOptions();
edgeOptions.UseChromium = true;
edgeOptions.BinaryLocation = @"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe";
var msedgedriverDir = @"D:\webdriver83.0.478.54";
var driver = new EdgeDriver(msedgedriverDir, edgeOptions);
driver.Navigate().GoToUrl("https://bing.com");
Thread.Sleep(3000);
driver.Close();

Note: Change the paths in the code to your owns.

Thank you for your suggestion. I am using selenium 3.141.0 in NuGet Package Manager. I am not able to find the version "4.0.0-alpha05" NuGet Package Manager. Could you share the steps to get the latest version

You could run Install-Package Selenium.WebDriver -Version 4.0.0-alpha05 in Package Manager Console to install it: i.sstatic.net/erupP.png. To open the Package Manager Console window, you could click View-> Other Windows-> Package Manager Console.
