If it's any consolation; I just tried logging in/joining using both the email (other than gmail) method and the "I don't use social media" method. and experienced nothing but failure and errors. It never crashed on me, but I certainly couldn't get anything working either. It told me I had succesfully "joined" using the "I don't use social media" route, but I still couldn't sign in (and haven't yet recieved the confirmation email that was supposed to be forthcoming).
It's unclear to me what the difference is between logging in via email and choosing "I don't use social media". They would seem to be the same thing.
Anyway ... it's not just you, if that helps at all.
