A simple fix so you can login!
So I found a work around for this issue I logged into eu.battle.net downloaded the desktop thingy and logged into that and i am able to login to WoW and play again and in the setting thingy on the top left you can set it to open wow in 32 bit so gg. back to what i was doing for now.
-edit
Opened up HB after making the desktop app open WoW in x32 bit and it works fine no problems for me. Hope this helps you guys.
