Client "shut down" when choosing summoner spell

I tried 2 normal game today in live client. It use old matching mode blind pick. When I chose summoner spell, as soon as i click my mouth at the botton, the client become dark and un-operated anymore. It quite similar to the situation in which a message box jumped out and we need to close it to continue, however, in my case the msg box is invisible. So after I click on any of the summoner spell the client would go into this stat and I can only quit the match and re-launch the client.

Idk if its a seldom case, hope roit to fix it
