Yes, this is the reason why it won't open.

Is there anyway to reset this trigger, so I don't have to go backwards hours and hours into the game and restart basically trying to earn all 6 statues?

No, not that I know off. I had to redo much of the game as well . This is basically the biggest bug in the game!
