Windows 10: Cannot log in for Cortana

Cortana asks me to log in (i assume to my microsoft account), but no log in screen appears. On one occasion, a blank gray screen appeared. But every other time that grey screen just appears and disappears so rapidly there is no chance to even see what it is.

Perhaps related: when I go to the Windows Store, i am also asked to log in to my account. But there is no login box there either, hence impossible to proceed.

a screenshot of the blank grey screen is appended.
