Unable to start Dais on 2nd room of Trialmasters Challenge

On the Trialmasters Challenge, with the Huntress, I am unable to start the second room of any corruption trial. Previously I would just left-click the Dais to get it to start, but no matter what I do, what keyboard button I click, what mouse click I use or despite whatever I arm my left-mouse click with, I cannot start the trial. I get past the first room fine.
