Question: I am using Version 81.0.4044.113 (Official Build) (64-bit). It was not happening before and the code was working completely fine. But after few days I ran it again and this error came. I am using these modules-> from selenium import webdriver from selenium.webdriver.common.by import By from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC from selenium.common.exceptions import TimeoutException import csv import time from tkinter import * def Authorization(): time.sleep(15) username = driver.find_element_by_id("userInput") username.send_keys('username') driver.find_element_by_xpath("//*[@id='login-button']").click() time.sleep(5) password = driver.find_element_by_xpath("//*[@id='passwordInput']") password.send_keys('password') submit_button = driver.find_element_by_xpath("//*[@id='login-button']").click() def Extractor(): time.sleep(25) integrated_release = driver.find_elements_by_xpath("//*[@id='versionArea']/div/table/tbody/tr[2]/td[2]") global integrated_release_data integrated_release_data = [x.text for x in integrated_release] impact_release = driver.find_elements_by_xpath("//*[@id='versionArea']/div/table/tbody/tr[5]/td[2]") global impact_release_data impact_release_data = [x.text for x in impact_release] build_platform = driver.find_elements_by_xpath("//*[@id='btkArea']/div/table/tbody/tr[2]/td[2]/span") global build_platform_data build_platform_data = [x.text for x in build_platform] def To_csv(): csvData = [final_data] with open('data.csv', 'a') as csvFile: writers = csv.writer(csvFile) writers.writerows(csvData) csvFile.close() def printtext(): global bugName bugName = e.get() print(bugName) def kinter(): root = Tk() root.geometry("500x100") root.title('xtractor') var = StringVar() label = Label( root, textvariable=var) var.set("Enter") label.pack() global e e = Entry(root) e.pack() e.focus_set() b = Button(root,text='submit',command=printtext) b.pack(side='bottom') root.mainloop() kinter() driver = webdriver.Chrome() bugs = bugName.split(',') driver.get("http........"+bugs[0]) bugname = [bugs[0]] Authorization() Extractor() final_data = a+b+c+d+e To_csv() count = 0 for bug in bugs: try: if count == 0: count += 1 continue driver.get("http:....."+bug) bugname = [bug] Extractor() final_data = a+b+c+d+e To_csv() except: continue  and I have installed the same version of webdriver as of chrome. Any idea how can I solve this issue?

Answer: This error message... ERROR:browser_switcher_service.cc(238)] XXX Init()  ...implies that call to on_init_ raised an error.  Analysis This error is defined in bluetooth_adapter_winrt.cc and was the direct impact of the changes incorporated within google-chrome as per the details available within the discussion Chrome no longer accepts certificates that fallback to common name  Solution Ensure that:  Selenium is upgraded to current levels Version 3.141.59. ChromeDriver is updated to current ChromeDriver v84.0 level. Chrome is updated to current Chrome Version 84.0 level. (as per ChromeDriver v84.0 release notes) If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.   Additional considerations However it was observed that this error can be supressed by running Chrome as root user (administrator) on Linux. but that would be a deviation from the documentation in ChromeDriver - WebDriver for Chrome where it is mentioned:  A common cause for Chrome to crash during startup is running Chrome as root user (administrator) on Linux. While it is possible to work around this issue by passing '--no-sandbox' flag when creating your WebDriver session, i.e. the ChromeDriver session as such a configuration is unsupported and highly discouraged.  Ideally, you need to configure your environment to run Chrome as a regular user instead.  Suppressing the error Finally, as per the documentation in Selenium Chrome Driver: Resolve Error Messages Regarding Registry Keys and Experimental Options these error logs can be supressed by adding the argument: excludeSwitches: ['enable-logging']  So your effective code block will be: from selenium import webdriver options = webdriver.ChromeOptions() options.add_experimental_option("excludeSwitches", ["enable-logging"]) driver = webdriver.Chrome(options=options, executable_path=r'C:\WebDrivers\chromedriver.exe') driver.get("https://www.google.com/")
