Game Crashing Bug That Riot Needs To Fix ASAP!

Not sure if anyone else is getting this, but ever since the last patch I have been getting this horrible bug. What does it do you ask? The whole game just crashes out of nowhere, freezes the game, and you can't even delete the client. It forces you to have to restart your whole computer, then log back in. Having to do this is an instant loss for your team, and it is not fair to anyone to have to deal with this. At first I had thought it could of been on my end, but everything on my end works just fine. If we can get this fixed, that would be nice. Its not fair to have to lose ranked games due to such a harsh bug on Riot's end.

Has anyone else ran into this terrible bug yet? If so, please let me know so maybe we can get Riot's attention and get this nasty thing fixed. Thank you for any help with the matter as well, it would be much appreciated. Tired of losing ranked games to this thing, and I don't want other people to have to go through the same pain.
