I ran into this same issue on Wednesday. Completed the latest raid, continued the quest chain, and attempted to take a party member's portal to Coerthas Central Highlands (CCH).

During the load-screen into CCH, my game crashes to desktop without error. Every time I attempt to log in, I get thru the queue, and as soon as the CCH load screen begins my game crashes again. This isn't due to yesterday (Thurs) patch, and was occurring for me on Wednesday.

When exactly did you crash? What zone were you loading into, if any? What zone are you trying to load in to on character log in?
