    • Does this happen only while running WebDriver tests or because of running WebDriver testing you can now only launch one instance?  Have you tried shift clicking the running instance in the taskbar?

    • This is happening when run test using Microsoft webdriver.
      if we open a website as follows in C# selenium

      1. EdgeOptions options = new EdgeOptions();
      2. options.PageLoadStrategy = EdgePageLoadStrategy.Eager;
      3. IWebDriver driver = new EdgeDriver("WebdriverPath", options TimeSpan.FromSeconds(20));
      4. driver.Navigate().GoToUrl(“”);

      If i run above blocks of code twice, it throws error “Unexpected error. Unknown error” second time on line number 3.

    • Hi Steven,
      Any updates on this would be a great help

    • Adding more to this issue:
      When we try to launch an edge browser in selenium it closes all other edge browser that we opened manually.
