My EU account is stuck, i need help thank you very much ^^

Recently i tried to get the Artas hero by beating Lich King with every class.

But, and i don’t know if there is a link, but since then every time i launch my game, it’s stuck on the door of Hearthstone, until the game disconnected me.

It’s a really weird problem and i don’t know what to do

I already tried to reinstall the game 3 time, and reinstal Battle.net countless time but nothing changed.

I don’t know if someone already had this problem before but i you have a solution it will help me a lot

Thanks you very much and have a nice day ^^.

(Sorry for the potential grammar mistake i’m not english).
