[CRASH][CLIENT] Janna bug in loading screen.

I was in loading screen and I was disconnected. A bug splat report shows up and I clicked send to developers. I then received this message saying that an Essential Asset to the game is missing. The LoL client is still running and when I click reconnect, it disconnects me from loading screen with the same message. I then restarted LoL and a message saying to reinstall league of legends. At this point I am panicking because I was in a ranked game. I then had the option to repair my launcher and so I did. Is there a fix to this bug? Or has it already been taking care of? I honestly do not want this to pop up in another ranked game. Thank you for you time.
