如何解决“ [警告]：连接到Chrome超时，正在重试…”]]

Question

• C＃.NET Framework 4.8控制台应用程序（32位）
• Edge（Chromium）80.0.361.69
• msedgedriver.exe（64bit，80.0.316.69）
• Windows 10家庭版64位1909 18363.720
• Selenium.WebDriver 4.0.0-alpha05

static void Main()
{

    var edgeOptions = new EdgeOptions
    {
        UseChromium = true,
        BrowserVersion = "80.0.361.69",
        BinaryLocation = @"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe"
    };

    var service = EdgeDriverService.CreateDefaultServiceFromOptions(Directory.GetCurrentDirectory(), "msedgedriver.exe", edgeOptions);
    using IWebDriver driver = new EdgeDriver(service, edgeOptions)
    {
        Url = "https://www.naver.com"
    };
    Console.ReadLine();
    //While the program is paused, I opened a new window manually and pressed enter on the console

    driver.SwitchTo().Window(driver.WindowHandles[1]); // this takes 30ms
    //After calling driver.SwitchTo().Window(), 
    //a message [1585376776.256][WARNING]: Timed out connecting to Chrome, retrying... appears on the console.

    var elements = driver.FindElements(By.Id("whatever")); //this takes 4030ms

}
以上是我的环境和代码当我运行程序时，

此消息出现在控制台上。如果我不切换到另一个窗口，但是每当切换到另一个窗口，都可以忽略不计，

[1585376776.256][WARNING]: Timed out connecting to Chrome, retrying... 
出现在控制台上。这会再次出现，并且下一个第一个driver.FindElements（）调用始终需要大约4秒钟。我用chrome测试了这个问题，但结果是一样的。我在Google上搜索了很多，但是找不到合适的答案。如何解决此问题？

[每当您借助selenium驱动程序加载某些页面时，驱动程序脚本都会等待页面完全加载完成。但是有时网络驱动程序需要3到4分钟才能加载页面，在这种情况下，您会在控制台中看到TimeoutException异常。
