Window keeps closing after running selenium

Everytime I run this code the window opens blank and then loads the required page for about 1 second before closing. 

from selenium import webdriver

driver = webdriver.Chrome('C:/Users/*****/Downloads/chromedriver_win32/chromedriver.exe')
driver.get("https://stackoverflow.com/")

An error has come up once or twice saying [268:10204:0208/163438.782:ERROR:broker_win.cc(55)] Error reading broker pipe: The pipe has been ended. (0x6D) but it only appears sometimes even though the code hasn't changed.

Any suggestions?

If you want your code to keep open your browser window then you can do the following which I mentioned in this post: Chrome browser closes immediately after loading from selenium

#if you find this effective then do mark it as useful

Thank You

One of the best possible workarounds is to set Sleep(), so that the browser doesn't close:

import time 

driver.get('https://www.google.com')
time.sleep(3000)  #this makes browser not to close.

I am using ChromeDriver 81.0.4044.138 placed in C:\Windows and this is whats working for me

from selenium import webdriver

class Stackoverflow(object):
    def __init__(self):
        self.options = webdriver.ChromeOptions() 
        self.options.add_experimental_option('useAutomationExtension', False)
        self.options.add_experimental_option("excludeSwitches", ["enable-automation"])
        self.driver = webdriver.Chrome(options=self.options)
        self.driver.execute_cdp_cmd("Page.addScriptToEvaluateOnNewDocument", {
          "source": """
            Object.defineProperty(navigator, 'webdriver', {
              get: () => undefined
            })
          """
        })
        self.driver.execute_cdp_cmd("Network.enable", {})
        self.driver.execute_cdp_cmd("Network.setExtraHTTPHeaders", {"headers": {"User-Agent": "browser"}})
        self.driver.get("https://www.stackoverflow.com/")

if __name__ == '__main__':

This error message...

ERROR:broker_win.cc(55)] Error reading broker pipe: The pipe has been ended. (0x6D)

...implies that the pipe is broken as if the browser side has been closed.

This error is defined in broker_win.cc within the Chromium code repository as follows:

Channel::MessagePtr WaitForBrokerMessage(PlatformHandle platform_handle,
                     BrokerMessageType expected_type) {
  char buffer[kMaxBrokerMessageSize];
  DWORD bytes_read = 0;
  BOOL result = ::ReadFile(platform_handle.handle, buffer,
               kMaxBrokerMessageSize, &bytes_read, nullptr);
  if (!result) {
    // The pipe may be broken if the browser side has been closed, e.g. during
    // browser shutdown. In that case the ReadFile call will fail and we
    // shouldn't continue waiting.
    PLOG(ERROR) << "Error reading broker pipe";
    return nullptr;
  }

The main reason you see this error is because the ChromeDriver controlled Chrome browser gets detected and the navigation gets blocked.

Solution

As a solution you may need to configure the ChromeDriver / Chrome with certain configurations so Selenium driven Chrome Browsing Context doesn't get detected.
