string path = string.Empty;
if (System.Environment.Is64BitOperatingSystem)
path = Path.Combine(System.Environment.ExpandEnvironmentVariables("%ProgramFiles(x86)%"), "Microsoft Web Driver");
else
path = Path.Combine(System.Environment.ExpandEnvironmentVariables("%ProgramFiles%"), "Microsoft Web Driver");

            return path;
        }
    }

...
IWebDriver driver = null;
EdgeOptions options = new EdgeOptions();
options.PageLoadStrategy = EdgePageLoadStrategy.Eager;
driver = new EdgeDriver(EdgeServerPath, options);
driver.FindElement(By.Id("main")).SendKeys(Keys.Control + "0");

The Selenium project does not develop or maintain the driver for Microsoft Edge. Issues and bug reports should be filed with Microsoft (http://connect.microsoft.com)

Hi jimevans, appreciate your support. Do you at least attempt to recreate the error? Could you double check if is an actual webdriver issue or the selenium client or both?

[jimevans]

I'm not able to recreate the error, no. I _do_ have an exception being thrown because the driver can't find an element with an ID attribute of "main", but that's not the issue you're describing here.

[cocasio]

Found a workaround, set the setting 'Open with' to 'A specific page or pages', 'Start page' default option do not work.

[Elmue]

The reason for an "unknown error" is when you start the edge driver elevated (as Administrator) which is not permitted. As it is very badly programmed it does not spit out any intelligent error message (the worst programming style).

still happening as of today .. exactly as @Elmue mentioned
