I just noticed that folding AQ here or even at the river at all means that I fold my entire range though because I'd always raise 77, 44, A7s, A4s OTF and don't have any other 4x in my range.
Is this still okay as an exploit vs a very strong line or should I at least consider calling with some of my AQ combos? The ones without the Qs i.e.?

snapcall turn , probably also snapping any non spade river

Interestingly if MP also has an A then theres only one Ace left in the deck. Sure MP could also have fds but with all of this im probably just call/calling non flush rivers. The guy is a fish who really knows what he's doing.

I'd cold 4bet pre. MP is continuing with 100% of his range vs this sizing and so you are going to be sandwiched in between 2 players which is always going to be difficult to play.

I'd prefer a 4bet, and fold if either of the 5bet.

Interesting that you all think this is a pretty easy call, call. I feel like barring any reads, min3bet, 1/2 pot cbet, pot turn and bet lets say >1/2p OTR n a 3way scenario is a pretty strong line which has AQ in pretty bad shape.

I'm 4betting preflop and folding to a 5bet. As played I think you can make an exploitable fold OTT. It's such a strong line for him to take. This is atleast AK imo.

Flat pre and fold turn. You are never ahead
