how about creating new user ,giving it BIAdministrator or BIAuthor role and then try to login with that new user? this might help if the issue is with the GUIDs associated with the pre-defined users
The issue might be due to mismatch of GUIDs between different environments. Have you tried refreshing GUIDs?
If not, try the steps mentioned in the below link
