Leagu of legends error

I’ve already seen this error in one post but it’s solution isn’t useful for me because the folder where the conf should be doesn’t exist.
My error is :
eague of Legends caused ACCESS_VIOLATION in module League of Legends

Read from location 00000000 caused an access violation.
