Windows Chrome/94.0.4606.71 - "Failed to decrypt the cipher text with DPAPI" with 0.12.1

[howardjones]

This seems to be #44 but that was before PR #48 which supposedly fixed it. I guess something has changed again since?

Python 3.9.5 on Windows 10.

I am loading cookies from a non-standard location, written to by my Selenium session:

  options = webdriver.ChromeOptions()
  options.add_argument('--user-data-dir=c:\\temp\\profile2')
  client = webdriver.Chrome(options)
  # ---
  cookies = browser_cookie3.chrome(cookie_file="C:\\temp\\profile2\\Default\\Cookies")  

and I can see a sqlite file where I am pointing with valid contents (I can browse the tables in pycharm)

You have to pass the key_file argument too to the chrome method. The key file is named Local State. And it should be on user data dir ('c:\temp\profile2\Local State' in your case.)
