The client is... [client] [crash]

i dont know how to explain it but i think this video is enough proof that its a bug

since people are not coming yet lets try and explain this from what i know. 1: when opening league it immediately closes and opens the crash page 2: it redoes 1 over and over again until i close it through task manager 3: re-installing and the hextech repair tool doesnt fix it.

i tried running the repair tool as an admin i un-instaled and reinstalled it and it didnt work so... [sg-lux-2] HELP ME PLZ [sg-janna]
