Client update crashes game on loading.

Sometime during patch 7.15 I noticed 1/5 games i play will just randomly crash my client completely. My screen will just go black after champ select and then I hear a windows error sound and a little error box saying "Check your internet connection". I am hardwired directly into the router. This has never caused an issue before. I cant recreate it 100% of the time but it only happens right after champ select is done and it is transitioning to the in-game side of league. This is a huge issue because now I get negative LP for leaving the game. I have already lost about 32 LP for "leaving" matches when in reality I couldn't even join the match to begin with. This is a huge bug and i can only seem to get rid of it by doing a complete client repair. I have done about 3-4 client repairs and this issue is still persisting. I have talked to a couple of my friends and they are reporting the issue as well Update. I was able to recreate the error. I was booted from a game when im in a duo queue. this error message is what showed up

Another update. Ive rebooted twice. and did a complete client repair about 5 times now. But looking at this just really makes me not want to play anymore. I have lost about 32 LP from "leaving" ranked matches and im sure by now your automated system is marking me as a bad sport/ someone that leaves games a lot. Im just trying to play. Usually people just have to worry about enemy players boosting or hacking. Turns out the real demon under the bed was clients crashing. [slayer-jinx-unamused]
