Error 500 when verifying TFA Code in 8.0.0

Originally I could not get into Gitlab using my TFA code from Google Authenticator (Authy). Could on the latest 7.14 build. I had to log in with an emergency code. Got in, disabled TFA, trying to re-enable and getting this error after entering the 6 digit code to confirm.
