No i have purchased ^^again^^ in steam instead of epic store and now multiplayer works perfectly fine. Epic games store is broken. I love this game so i didnt mine buying it second time for support(and able to play the game). So if there is anyone out there having the same issue just buy steam version thats the only way to fix this problem right now. And as i searching for a solution i saw a thread from a year ago at the turkish taleworlds forum with same bug so there is no one trying to solve it atm i guess.
