Demon form causes game to disconnect

I just got my Demon form skill, and the first time I tried it, game just disconnect straight away. At first I thought it was just POE2 being POE2 no big deal. But then when I relog into game and change back to human form game disconnect again. So I tried 3 different time to turn into demon form and game would just disconnect . I have restarted my pc, exit and reload the game . Nothing works . Anyone has the same issue ??
