I was doing the Nightfae campaign, during the theater quest the spell Blizzard (227723) was applied to me as permanent debuff as part of the story and was supposed to be removed just a few seconds later, but I had entered a dungeon in the middle of the sequence and now the debuff is permanently applied to me, making me unable to move. I had finished the quest since then, and I’m still bugged.
I had tried logging out and using the unstuck self-service, but I am still unable to play the game.
