After Hazrat Isa a.s, were there prophets or only guardians/vicigerents?
Our belief is that there is no time devoid of a divine guide, however, the guide is not necessarily a prophet, he could be a successor. As for the time period between Isa (p) and the seal of prophets Mohammad (pbuh&hp), some Muslim theologians believe that there were prophets, others believe that there were no prophets but successors.
