Stuck in Purifier fight

Hi guys, I faced this issue fighting the Purifier with Maven, after completing the face 2, the guy was stuck, waiting for the Elder to take him into the face 3:

I have made a video here: https://youtu.be/FYTl4SGgQq8

showing the fight was stopped waiting for the Elder

Thanks and bests!

Multiple threads for the same issue already, have to wait for GGG to fix it.

It because of Delirium and Elder together. Disable Delirium or remove the neverending keystone and manually end it before the boss fight.
