The most common reason for the "Invalid token" problem while logging in, is the 2FA feature does not recognise your 6-digit code form the phone authenticator app because the time on your computer is not exactly the same as on your phone

If there is a more than a 30-second difference (the code in the authenticator app is generated every 30 seconds), the 2FA feature will not recognise the entered code as the correct one. 

Please go to time and date settings on your phone and check that the time is set to "Automatic". When both times are synchronized, your 6-digit code from the authenticator app should be accepted by the 2FA feature.
