The Cuachic Vault Zolin And Zelina

They wont stop chanting while I'm in their arena and cannot fight them. Can't progress into endgame without fighting them but cannot due to this bug. I've tried restarting at checkpoint, dying to a mob, exiting the game, restarting computer, exit to character selection, exit to log in screen, nothing works. Please fix this bug I really don't feel like starting a whole new character just because these two are bugged and I'm soft locked. https://imgur.com/a/ogynQqX
