Pretty sick hand, obv you only lose against 5 combos (Q8 or Q7 isn't in his range but QQ probably is if he is nitty). His 3bet sizing really looks nutzy espcially 5 way and I except him to just shove a combo draw. It really looks like QQ.

If we put him a range of 77/88/QQ, T9ss, JTss, AQss, KQss, AKss we have 27% equity, if we add AJss, ATss, KJss, KTss, QTss, QJss we now have 38% equity. Because of his nitty style I don't see a lot of other possible FD in his preflop range.

So in fact it's a pretty easy fold (and we are not even sure he go broke with all of the FD that I put in his range).

Would CO ever hold QQ here? Even a nit will 3bet that hand even against UTG. Other sets a pretty unlikely.

If we remove QQ of his range we only have 47.50%, so it's probably ok with the money we already put in the pot but he has to shove all his possible FD and never have QQ.

once we remove QQ from his range we are getting the odds to call. but based on the description of the player this would be a really strange play for him to make with anything worse than Q7 suited...

I'd lead the flop given it's 5way. As played, easy fold - I seriously don't get how can you justify doing anything else here - CO leads into 4 people, there's a call behind, and yet, you still XR - how strong does this play alone look in the first place? And the guy still min 3bets you with the BU left to act. What worse hands do you expect to see here, honestly?

Sick spot.
The suspicious thing is his min3bet, this is never a draw imo so we probably have to fold.
I would be more inclined to call a shove than this min3bet.

As played it's a trivial fold, both vs min3b and 3b shove I think (assuming he is a nit).
xR overplays our hand, think that xC is a better option. Ranges are really tight in 5way pots.
Agree with taaazz that leading flop is the best option. Hope that one of the recs comes along. If a nit raises, fold.

leading flop pretty terrible in this spot imo pretty sure its not even close

Well villain is not raising with air thats for sure. So either he has better two pair (we are almost dead) or a set (we are dead). So at best we are gonna be flipping. I think it is a fold as played.

Leading is also not greatest thing to do, cause we are gonna get raised often by combodraws, FDs and SDs.

The problem is 1) yea, we got two pair ! wohouuu ! 2) but under these circumstances and on this board it sucks ass ;)
