Hi, a significant crack has developed in the drywall between
the living room and kitchen. I think the weight of the pot rack
has, over time, contributed to the crack, but I'm not taking it
down.. I've repaired smaller cracks with spackle, sanding and a
coat of paint, but since this is larger, and the pot rack will
still be hanging there, I want to make a more robust fix, if
possible. IS there a better way to fix the crack ? Thanks

I doubt your pot rack did that. Looks more like foundation movement to me, and if it were my
house, I think I might want a structural engineer to have a look. There's a LOT more going
on there than just "a crack in the drywall".
