Need vestage help! CO op please!

I just beat the boss in Bramis Castle. I'm assuming I'm close to the end of the game. I have 24 vestages open and as far as I know I've completed them all. Maybe I missed some? There is no (!) on any of them and I don't know where else to go. Can anyone help me please? I'm playing on PS5 and my name is SuchRemorse if anyone wants to play. Just send me a friend request and we can do this. I'll help back anyway I can.
