Can't Add GMail Account

hi, deleted gmail account since acting quite bit (for example, in system preferences couldn't tick or untick -it blank- , couldn't add or delete accounts). deleted mail, ical, etc individually, tried add account back, got issue in video attached, deleted .plists (basically matched search ical, address book, mail or sync in ~/library/preferences), rebooted , still same.

p.s.: tried couple times , i'm sure wrote email , password correctly, tried changing name.
