Hello,
I seem to have fallen into a glitch that every time I login it crashes my game. I was doing a quest to deliver Sylvanas Windrunners Necklace to her as a Bloodelf. As I was going down to her chambers my game crash and now every time I try to log on to my character it immediately crashes as soon as I spawn.

that's pretty generic ctd, it means that game can't "load" or "understand" some file from game directory, something along those lines, there are lots of reasons for that
try removing it from torrent/close torrent client, if it's there
try simply restarting your pc
try deleting WTF folder (actually backup it somewhere, so you can put it back in and keep your settings later)
check if your antivirus didn't get mad at it and removed some file
try updating/reinstalling drivers. graphics, maybe audio too
