我遇到一個奇怪的問題，當我單擊打開彈出窗口時，代碼會凍結 10-12 分鐘，然后與彈出窗口正常交互。以下是完整代碼：System.setProperty("webdriver.chrome.driver", System.getProperty("user.dir")+ "\\exe\\chromedriver.exe");      driver = new ChromeDriver();driver.manage().window().maximize();driver.manage().deleteAllCookies();driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS);driver.manage().timeouts().implicitlyWait(120, TimeUnit.SECONDS);driver.get(prop.getProperty("https://genpact-qa-smartit.onbmc.com"));          driver.findElement(By.xpath("//*[@id='okta-signin-username']")).sendKeys(userid);driver.findElement(By.xpath("//*[@id='okta-signin-password']")).sendKeys(pwd);driver.findElement(By.xpath("//*[@id='okta-signin-submit']")).click();driver.findElement(By.xpath("//a[@id='header-search_button']")).click();driver.findElement(By.xpath("//input[@id='globalSearchBox']")).sendKeys("CRQ000000029504");Robot robot=new Robot();robot.keyPress(KeyEvent.VK_ENTER);robot.keyRelease(KeyEvent.VK_ENTER); driver.findElement(By.xpath("//a[text()='View Full Change']")).click(); Thread.sleep(3000); driver.findElement(By.xpath("//div[@title='Print']")).click(); Thread.sleep(3000);Actions a = new Actions(driver);a.moveToElement(driver.findElement(By.xpath("//button[contains(text(),'Print Change')]")));a.click();a.perform();Set<String> window_handles=driver.getWindowHandles();String child=null;System.out.println(window_handles.size()); for(String handle:window_handles) {     child=handle; }單擊“打印更改”10-12 分鐘并單擊新彈出窗口上的“打印”按鈕后，以上代碼將凍結。操作系統：Windows 10；瀏覽器：Chrome 77.0.3865.90；硒 3.141.59任何幫助，將不勝感激。
