Disclaimer: this is purposefully obtuse.

Other effects in the game which explicitly state they kill you:

Shadows, succubi, massive damage, death saving throws, beholder death ray (notably not even their disintegration ray kills you), power word kill, vampires, mind flayers, night hags, drow inquisitors.

Clearly, if they intended for disintegration to kill you, they’d have said so. Since specific overrides general, and there is no general rule that disintegrated creatures are dead, I rest my case. QED.

      A disintegrated creature and everything it is wearing and carrying, except magic items, are reduced to a pile of fine gray dust.

      Going from creature to pile of fine gray dust sounds like changing to me

        It changes your shape, yes! Same as Polymorph does, for example. That doesn’t mean you’re no longer a creature. See True Polymorph for example, which can turn creatures into objects. And it’s a higher level spell! Clearly the devs intended that ability to be higher magic.
