Character stuck in Trialmaster fight

Hello, I'm playing chronomancer with temporal rift, and I have started Trialmaster boss fight in the chaos trial.

I enter the 1st room, the elevator takes me way up, boss talks for a bit, hits me once, i press temporal rift and the game returns me into the room bellow, only now I can't go up the elevator. I can't exit the trial with a portal, game won't allow it. I tried logging out and back in, still stuck. I have nothing to die to.

Help plz!
