selenium error when entering text in textarea?

Question

C++ / C#

I tried to write a program that enters the instagram site with cookies and writes a comment to the post.
Everything works fine, I click on the textarea (input but there is textarea) the click is counted and when the program starts to enter text the error comes out ( element is not attached to page document )

xpath are written correctly

Code:

driver = new ChromeDriver();


            driver.Navigate().GoToUrl("https://www.instagram.com/p/CRmiXY8lkwD/");
            driver.Manage().Cookies.AddCookie(new Cookie("sessionid", "48257564335%3AxqVRD0uGeXxIor%3A25"));

            driver.Navigate().Refresh();
            Thread.Sleep(1500);

            var input = driver.FindElement(By.XPath("//textarea[@class='Ypffh']"));
            input.Click();
            input.SendKeys("test spam");

            Thread.Sleep(1200);
