Kha'zix bug? Screwed my whole ranked team.

So we were loading into a game, and as we all hit 100% I got an error message that said "an essential asset to the game could not be loaded," the champion Kha'zix, and that I had to reinstall and repair my client. So...thanks to that, I missed our game and our team is losing because the client isn't repairing. My guess is that everyone on my team is going to report me because I'm "AFK" because this client bug even though it's not my fault. My friend is duo-ing with me and he told the teams, but I still am unsure what to do. Anyone else gotten this?
