I\'m setting the user director to be my default User data directory as such (so I don\'t have to worry about entering passwords to sites and logging in each time):
you need to remove /Default/ because its not valid directory for --user-data-dir it is for --profile-directory
/Default/
--user-data-dir
--profile-directory
options.add_argument('--profile-directory=Default') # or options.add_argument('--profile-directory=other_profile')
