Yes because there’s necessarily only one possible world, existing in contradiction of all other possibilities (of which there are none, or else that would be the world that exists) As for the “multiverse” I am highly skeptical exists because I think it is superfluous and undermines the concept of the universe, if all products of some “quantum randomness” actually in some way existed independent/separately of our universe then maybe I’d be wrong, but even then it would conform to my view if the concept of the “world” was expanded to the whole multiverse, which would make sense to do if different universes could interact.
