League Client Bug (Issue is Spreading)

Hello my name Is Kemlordchaos, im making his post on boards to raise awareness about a major bug that is beginning to spread among the league of legends clients. The bug in question is that the client crashes itself upon start. I myself experienced this bug when ever i went in the login screen of the lol client, but i was able to repair my cleint and it seems to be fine now. However this bug has become worse a friend of mine(who shall remain anonymous) claims that his client crashes immediatlely and doesnt even allow him to choose repair client to try and fix it. Ive seen and heard of other people having this issue so it means that what ever is happening with the client is spreading and may in fact become a major issue later ( i truly hope not). Thank you for your tme
