    driver.SwitchTo().Window(driver.WindowHandles[1]); // this takes 30ms
    //After calling driver.SwitchTo().Window(),

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

}

Above are My environments and the code
When I run my program, 

Starting MSEdgeDriver 80.0.361.69 (11b2f9c770113c9712ab7dffaca9ea3596d0deb3) on port 13626

this messages come up on the console.
It's negligible if I don't switch to another window but whenever switching to another window,

[1585376776.256][WARNING]: Timed out connecting to Chrome, retrying...

appears on the console. this appears again and the next first driver.FindElements() call always takes around 4 seconds.
I tested this issue with chrome but the result was the same.
I've googled a lot but I couldn't find any appropriate answer.
How can I resolve this issue?

Whenever you are loading some page with the help of selenium driver, then driver script wait till page is completely loaded. But sometime webdriver takes 3 to 4 mins to load page, in that case you will see TimeoutException exception in your console.

When Page Loading takes too much time and you need to stop downloading additional subresources (images, css, js etc) you can change the pageLoadStrategy through the webdriver.

By default, when Selenium loads a page, it follows the normal pageLoadStrategy.

System.setProperty("webdriver.edge.driver","E:\\edgedriver.exe");

edgeOptions options = new EdgeOptions();
options.setPageLoadStrategy(PageLoadStrategy.NONE);

driver = new EdgeDriver(options);
