Crash during champ. select, followed by the inability to reconnect.

The title.

I'm fine with taking a leave or two every week for a shitty and really irritating bug where the client freezes entirely and forces a force close, but when it happens when I'm selecting my summoner spells as the Jungler and forces me to try and play the role without the tools needed, followed by being completely unable to reconnect to the game for like ten minutes afterwards, and THEN followed by you reconnecting and a Fizz just killing you with one auto-attack because you're so under-leveled... ...then we have a goddamn issue.

Riot, I don't care what windows updates I have, this is unacceptable.

Edit: I don't install most updates because a few select ones I can't take the time to narrow down of the three-hundred, completely shut my ethernet port down for some odd reason.
