The 1D opening followed by 2NT is probably an underbid. The hand is worth much more than a 18-19 bal. If we are to hide the 7-bagger, then at least let’s open 2NT. Otherwise, I am not sure if the hand qualifies for a 2C opening for you (strong 2 in a minor) or a multi 2D if you play it.
The rest of the bidding is not really sensible. Knowing 18-19 bal opposite, W, despite having a nice hand, has insufficient combined material for a slam and should just bid 3NT. East is probably trying to recover from his earlier bidding and takes a (very) wild shot at 7NT when all they could be facing is sth like Qxxx Axxxx x Jxx.
I guess I’d reach 6NT with my partner. Of course, had I known there was no DK in the pack...
