I can confirm that after the latest WoW patch last night 10.0.5(47884), my WoW is now working again. Thanks to any propeller heads at Blizz that fixed the bug and good luck to all those who did have the issue I hope it is fixed for you as well.
Shadow this issue is long fixed. are you even crashing at login or is app just hanging/bouncing forever? if it’s bounce, there is a new thread on that issue but it’s a completely different one that crashing out with the errors in this thread
