python - How to use Selenium to download from a Web with certificates while locking the screen

Question

I'm trying to use selenium to download files from a webpage that requires a certificate. I have multiple certificates on my computer so every time when there is a pop-up window, I need to choose the right certificate to access the content of that webpage. For now, when the computer is not locked, I can run selenium and perform all these tasks automatically without issues. But after running my code script and if I lock my screen, the following errors encounter:

Exception in thread Thread-1:
Traceback (most recent call last):
  File "C:Userslmsunanaconda3libhreading.py", line 926, in _bootstrap_inner
    self.run()
  File "C:Userslmsunanaconda3libhreading.py", line 870, in run
    self._target(*self._args, **self._kwargs)

    failSafeCheck()
  File "C:Userslmsunanaconda3libsite-packagespyautogui\__init__.py", line 1257, in failSafeCheck
    raise FailSafeException('PyAutoGUI fail-safe triggered from mouse moving to a corner of the screen. To disable this fail-safe, set pyautogui.FAILSAFE to False. DISABLING FAIL-SAFE IS NOT RECOMMENDED.')
pyautogui.FailSafeException: PyAutoGUI fail-safe triggered from mouse moving to a corner of the screen. To disable this fail-safe, set pyautogui.FAILSAFE to False. DISABLING FAIL-SAFE IS NOT RECOMMENDED.

I can make this error go away by freezing my mouse. but it seems selenium cannot deal with the certificate pop-up window anymore after I lock my screen. Does anyone know if there is a solution? Thank you.

```
def threaded_function(url, browser):
    # Calls the website
    browser.get(url)
    return


def threaded_function2():
    global cert_num
    # give enough time so that the pop will appear before the press
    time.sleep(10)  # this needs to be hardcoded, if pass in as a parameter, thread error occurs
    # choose the right certification
    for i in range(cert_num):
        pyautogui.press('down')
    time.sleep(2)
    pyautogui.press('enter')
    return

while ind2 < 5:
    try:
        if ind2 != 0:
            print(f"Retrying open {folder_name_2}, {ind2 + 1}")
        browser = webdriver.Chrome(driver_directory)
        # Check version of msedgedriver.exe and Edge
        str1 = browser.capabilities['browserVersion']
        str2 = browser.capabilities['chrome']['chromedriverVersion'].split(' ')[0]
        if str1[0:2] != str2[0:2]:
            print("please download correct msedgedriver version")
            return
        print("Selenium operating starts...")

        cert_num = int(input_df[cert_end + '''].values.tolist()[0]) - 1
        cert_dir = input_df[cert_end + '''].values.tolist()[1]
        thread2 = threading.Thread(target=threaded_function2)
        thread2.start()

        thread = threading.Thread(target=threaded_function(url, browser))
        thread.start()

        thread.join()
        thread2.join()
        if ind2 != 0:
            print(f'The issue is solved, reopen window for {folder_name_2} successfully.')
        ind2 = 5
