Fucking no. I've literally thought about all the massive, multiverse-shattering issues that the Many World's interpretation have and how it makes absolutely no fucking sense at all so many times my brain's just basically numbed itself to me having to constantly go back to the memories of how dumb it is. Long story short, if it was real we'd literally have to have a 1/infinity chance of getting the ONE normal world with absolutely NO strangeness to it, to not land in a universe where sharks with lasers for eyes just suddenly start eating people for shits and giggles and shatter every known physical law with Quantum technology cuz they can or some other insane thing, because by the nature of the multiple world's hypothesis, literally every single conceivable and inconceivable world to ever exist exists, and there's an infinite replica of every single one of those universes as if there was literally no difference in between them. When you take into account the world's where one particle collision caused a molecule to go another way and boom new universe, and the fact that- even by LESS radical versions (Like one the states that there aren't INFINITE universes, only a new one for every choice a human makes) that just asks questions like why does electricity sparking inside a fat hunk (our brain) suddenly create a new universe when electricity firing inside carbon atoms of similar or the same makeup not do the same thing? There's so many unanswerable, system-breaking questions that any "Physicist" or variation of a physicist (Like Quantum Physicists) should have their doctorates taken away if they honestly, openly state they think it's real, because it's such unfathomable bullshit that anyone pretending to have something that takes that much work and just general capacity for intelligence, like a Doctorate, that thinks this could honestly be real is straight up lying and just two monkeys in a coat and mask.
