The Many Worlds, or Multiverse interpretation of QM has traction because it solves a problem. Specifically a problem relating to wave function collapse. I won't go into all that here, and doubtless if I did @Polymath257 would be along to tell me I've misunderstood. Which perhaps I have, but so have we all, for there are many things which surpass all understanding.
Superdeterminism solves the same problem in a completely different way. And there are other QM interpretations, and very little consensus among quantum physicists as to which is the most accurate description of "reality" at the sub atomic level. Or even what the problem (of wave function) is, or what it means.
Another aspect is that it is possible to do QM with a wave function that doesn't change at all. Instead, the 'observables' change over time. The end results are exactly the same, but which things change is different. And there are 'mixed' versions where both the wave function and the observables change over time.
The point is that all of these different interpretations lead to *exactly* the same observational results. There is NO WAY to distinguish between them by way of observation.
And, frankly, at that point, it becomes meaningless to adopt one interpretation or the other except when they simplify the actual calculations.
What I would say is that 95% of the 'paradoxes' of QM come from trying to make sense of it with classical ideas. If you think of things having definite properties and being in definite locations at all times, you *will* run into paradoxes because that is NOT how QM describes things. The problem isn't with QM, it is with the outmoded metaphysics saying what things 'should' be like.
ANY time you read about information going backwards in time, or instantaneous signalling, you *know* someone is trying to use classical concepts where QM applies. And that is, in and of itself, a huge mistake.
Perhaps the puzzles and paradoxes posed by QM, and looking the other way, of black holes and dark energy and dark matter, will begin to be resolved; only to be replaced with a completely different set of puzzles and paradoxes.
Yes that is how science tends to progress: we resolve some puzzles and paradoxes only to find new ones.
Meanwhile, we humans will continue to wrestle with the nature of the universe, it's first cause, and our place in it. Logic and reason are not the only tools we have been given to help us make sense of all that, or of our own little lives; there will always be a place for what has been called "The Language of the Heart".
A very poor way to find out things about the real world (as opposed to figuring out what you want to do).
