The email id for that User seems to be a problem, so try these

reset their FB social login settings
can the User login via Github Google or Frappe?
can other users login ok via FB?

That user doesnt even have an account, i was trying to create a new user via fb login and that error came out and i dont use google or frappe for login i want only fb

Your goal here is to exercise the code, to eliminate that as the root cause of your error.

But so far your user data settings seem to be the cause of the problem not the oauth login code?
