Counterexample: I go to sleep (lose consciousness) and wake up again. QI seems to predict that I would never fall asleep, because I stop observing when I’m asleep and so QI would force me into universes in which I don’t fall asleep. Timeless QI has no problem with me falling asleep and then observing I’m alive and awake hours later.

I don’t think advocates of QI generally mean by it what I think you’re taking it to mean.
In terms of conscious experience, dreamless sleep and death feel similar, as far as I know.
