I probably have this wrong but maybe this will help others to the right solution.
There are many many forks in the road here. Lets try the highway first:
Say East decides to win the ♦A and continue with a benign club. Declarer wins hooks the diamond and East does best by blocking the suit by covering. Win the diamond in hand and knock out the ♣K. I suppose West's best defense is low spade (but this leads to offramp 1 - see below) but declarer can win in hand cash the clubs play a diamond to the 8 and exit a spade to honor which West wins. The defense has a choice of putting declarer back in hand and taking 2 spades, 3 diamonds, 3 clubs. Declarer can exit the low spade and West must return a heart for #9. A heart return fares no better. Declarer can rise with the A, which also blocks the suit, exit a heart. East must put declarer in hand at this point.
Offramp 1. West returns a heart instead of a low spade. Declarer can rise with the Ace blocking the suit (pitching a spade), take the diamond 8, and play a spade, while the hearts are still blocked. West can win, cash their heart trick, but now East must win and put declarer in hand with a spade or a diamond.
Lets try another road out of town, which was my first impulse. It looks apparent for the defense to attack entries to the closed hand by winning the A♦, and shifting to a spade immediately. West wins, and plays back a spade. Declarer in hand at this point.
Lets try a ♣ to the A, ♦ to hand (again covered) J♣. West wins, and...?
I'll continue this later. (Sorry - went to edit this and the text went haywire)
