[CLIENT] Champion Select Freeze

Description: The client sometimes freezes in champion select. It seems to happen when I have just clicked to ban a champion. I have experienced this in both the old champion select (when I click the champion icon) and the new champion select (when I click the orange Ban button). In the case of the new champion select, the sound an animation that should accompany my click just barely start to play, then the client goes frozen. It says it is not responding.

Patch: This started happening this patch (6.7). I had never experienced this issue before then.

Steps to Reproduce: Get into champion select, ban a champion.

Frequency: Occasional; maybe once every 10-20 games
