Bug Splat (Any key press within the game, crash to bug splat)

Any key press from the keyboard within game leads to the client crashing and bug splat appear. Mouse clicks are an exception. I have submitted two to three reports and as well restarting client, then pc, then running in client in admin, and lastly the client repair tool. Problem not fixed. I was able to play a game just before. Considering that there where other issues with connection earlier, I have a hunch this isn't isolated?

--- Update --- Game ended, and I'm reported with a leave. Will I have an exception?
