I play this very differently.

Preflop - minor mistake. raise a little more. Often, 4xBB suffices but you want to chase out weak aces and have to adjust accordingly given the couple of limpers ahead of you.

The flop - no mistake there. you are OOP with a very bad flop. A probe bet is too dangerous with 2 opponents. I check and fold if bet at.

The turn - biggest mistake. Your bet was WAY too small. The info you got on the flop tells you you likely have the best hand here (even a weak ace should have bet half the pot on the flop). And now there is a flush draw. Make a pot-sized bet to give clubbies incorrect odds.

River - second biggest mistake. now you have a medium-weak hand given the board. An ace (even though they made like they didn't have one) and now the flush draw hit. A bet makes no sense. Anyone who can't beat your kings is folding and anyone who can is calling or raising. Check and hope it's checked down.
