Can't type in chat, ward, or ping properly since patch

When I press enter to chat, it does nothing. No chat box comes up.

When I try to ping, the mouse goes slowly around the ping wheel. Very, very slowly around the wheel. So it takes me literally 2-3 seconds to ping properly instead of < 1 second.

When I ward, a lot of the time my wards go completely somewhere else. My ping is only a steady 60.

I've played two PvP SR Draft games with this happening. On the first game load, I got a bug splat crash when the game loaded. On the second game I got no crash.

I've been playing for a long time and this is the first time I've never been able to chat or ping properly. No, I have no chat restrictions. That wouldn't explain thewarding and the slow pinging anyways.
