Is there any way to solve this?

I posted about this before on here but I didn't get much help, I'm also too far gone in the game to revert save files (aka I finished the game like last year and I've come back to it) what do I do about dealing with a missing collection chest, the quest is Mary Portman's cellar. About a year ago (maybe idk) I did the quest and when I opened the chest, I got nothing out of it, and the chest didn't register as opened, I came on here to ask for advice but didn't get much help. but now that the game has been out for a while, maybe there's a solution?

I cant redo the quest as its done, I've killed the foe, completed it, but the chest is stopping me from having complete 100% in my eyes. When I go back into the quest location, the chest appears on the map like its unopened, but in the actual game, the chest is opened and cant be interacted with in any way... not sure what to do about it yk
