回答by Krishanu Chakraborty
this error is due to the incompatible ChromeDriver version and the Chrome browser version that you are using. Please use the latest Chrome driver.exe (v2.41) with the latest Chrome browser version 68. It has worked for me.
此错误是由于 ChromeDriver 版本和您使用的 Chrome 浏览器版本不兼容造成的。请使用最新的 Chrome driver.exe (v2.41) 和最新的 Chrome 浏览器版本 68。它对我有用。

@Samraj Downgrading to Chromedriver 2.38 worked for me on Windows 10 Chrome 66.0.3359.181
@Samraj 降级到 Chromedriver 2.38 在 Windows 10 Chrome 66.0.3359.181 上对我有用
Just try Downgrading or Upgradingthe Chromedriver versionsaccording to the page chromedriver.chromium.org/downloads
刚刚尝试降级或升级的Chromedriver版本根据页面chromedriver.chromium.org/downloads
And download the corresponding versions from this page chromedriver.storage.googleapis.com/index.html
