No. If we assume that you have to target the wall it would at the very least stop after destroying the wall.
But by RAW, you can’t even cast it on something behind the wall, because you cannot target something (or someone) with a spell if they are behind total cover. Total cover is created by being completely behind an obstacle (like a wall). This counts even if the obstacle is invisible.
Furthermore, if you chose an invalid target for a spell, you still expend the spellslot but there will be no effect. So you’d actually spend a sixth level spell a lot to achieve nothing.
I would not recommend doing it this way, but that’s what the rules say.
Crawford also rules that See Invisibility doesn’t remove the advantage/disadvantage on attack rolls because it doesn’t say so in the spell’s effect, so… Yeah, I always ignore what he says.
That one has nothing to do with Crawford far as I’m aware. It’s just plain stupid interaction of several rules. You are definitely intended to be able to just cast disintegrate on the wall.
Some rules are intended in a certain way and just handled poorly. The above case is (I personally think) one of them. Others are actually intended to work a certain way because of designing aspects (like verbal components having to be said at a normal volume) but people simply decide to ditch them anyway, because they like something else better. Both are valid, but they are different.

And this is why my group is ok saying “that rule is profoundly dumb” and ignoring it while suspecting Crawford of being involved.
