Zul'jin Bug the game

I was playing a normal ranked game and everything was going well. My opponent was a Warlock almost in the middle of the game, the warlock used the Renounce Darkness card and changed into a hunter and after a few more turns he used the Zul’jin card, nothing happened in the game but his turn never ended. The game froze waiting for my opponent to end his turn. I have screenshots and videos but I don’t know how I can post that content in the forum.
