RSelenium+Chrome频繁关闭目标窗口

问题：使用RSelenium+Chrome爬取数据时，目标窗口频繁关闭。错误提示：
Selenium message:no such window: target window already closed
from unknown error: web view not found
  (Session info: chrome=84.0.4147.135)
  (Driver info: chromedriver=2.33.506120 (e3e53437346286c0bc2d2dc9aa4915ba81d9023f),platform=Windows NT 6.1.7601 SP1 x86_64)

Error:          Summary: NoSuchWindow
          Detail: A request to switch to a different window could not be satisfied because the window could not be found.
         Further Details: run errorDetails method

问题分析：因为Chrome浏览器版本和ChromeDriver版本不匹配导致。
解决办法：
方法1.检查Chrome浏览器是否有更新
打开Chrome浏览器—自定义及控制—帮助—关于Google Chrome

方法2.重新选用合适的ChromeDriver版本
