Get stuck with scorpian boss at trial of the sekhemas

I ran around the room when the boss had 1/3 of its health bar left. Then the boss transitioned to the phase where it digs into the ground but got stuck outside the door. I couldn’t do anything and had to start over with less than 1000 honor. Any suggestions or fixes?
