Candulhallow's Tombstones (Stuck end game)

[Tybaulk]

I'm stuck at the end of the game and I'm not able to advance, in the mission to get Orin's Netherstone I need to deliver Gortash's hand to Candulhallow's Tombstones, but to enter you need to roll a die to locate the hidden door, but I've already used all the characters and the "glitch" even though I come back save, it keeps failing, and I can't get out of the place, can you add another way to get into Candulhallow's Tombstones, or take this test with dice ?

Doesn't pushing the button behind the painting open the door even if you fail the roll? There's a button behind the skull painting. (If not, I don't know what else to try)

It worked, I didn't know the button existed... thank you soo much !
