hot keys quit working [GAME PLAY]

Hello Riot,

so about once every 5 to 10 games I'll enter a game and none of my hotkeys work with the game. The solution is to disconnect and then reconnect which sometimes means when I get back into lane I'm two to 3 levels behind. In my most recent game this happened to me, and near the end of the game my support went through the exact same thing, and its kind of hard to disconnect and reconnect when your nexus is under siege. This bug literally cost us a game where I had over 20 kills. if it was one instance I wouldn't care but as I keep seeing it happen to myself and multiple players I hope it can be quickly resolved.

I don't have a photo of it, nor am I sure why it keeps happening or how to cause it.
