selenium.common.exceptions.WebDriverException: Message: An unknown server-side error occurred while processing the command. Original error: Failed to start Chromedriver session: An unknown server-side error occurred while processing the command. Original error: unknown error: unable to discover open pages

contexts = self.driver.contexts
print(‘context=‘, contexts)

context= [‘NATIVE_APP‘, ‘WEBVIEW_com.XXXX.XXXX‘, ‘WEBVIEW_com.XXXX.XXXX:xg_service_v4‘, ‘WEBVIEW_com.tencent.mm‘]
