Selenium: WebDriverException:Chrome failed to start: crashed as google-chrome is no longer running so ChromeDriver is assuming that Chrome has crashed

Question

Recently I switched computers and since then I can\'t launch chrome with selenium. I\'ve also tried Firefox but the browser instance just doesn\'t launch.

This error has been happening randomly during my test runs over the last six months (still happens with Chrome 76 and Chromedriver 76) and only on Linux. On average one of every few hundred tests would fail, then the next test would run fine.

Unable to resolve the issue, in Python I wrapped the driver = webdriver.Chrome() in a try..except block in setUp() in my test case class that all my tests are derived from. If it hits the Webdriver exception it waits ten seconds and tries again.

It solved the issue I was having; not elegantly but it works.

from selenium import webdriver
from selenium.common.exceptions import WebDriverException

try:
    self.driver = webdriver.Chrome(chrome_options=chrome_options, desired_capabilities=capabilities)
except WebDriverException as e:
    print("\nChrome crashed on launch:")
    print(e)
    print("Trying again in 10 seconds..")
    sleep(10)
    self.driver = webdriver.Chrome(chrome_options=chrome_options, desired_capabilities=capabilities)
    print("Success!\n")
except Exception as e:
    raise Exception(e)
