I googled your question and received the following answer, “There is no explicit statement in the Gemara that Nevuah will not return until Moshiach comes however it is universally accepted that this is true.” Of course Chabad isn’t part of the universe since it’s on planet Yechida which is in a different solar system. Please provide your quote from Rambam. I’m certain that it’s another distortion. Checkmate.
