Client keeps resetting itself [BIG BUG]

Ok I opened my league client up a few days ago and before the log-in screen could appear, the client seemed to be repairing itself. I didnt perform this command as I know that players can repair the client. It just did it by itself. For no reason...

After logging in, the client reset all of my setting. Language filter was reenabled, ALL of my runes that i made were gone, etc. Luckily for actual gameplay, none of my hotkeys or binded keys were reset, or I would have been really upset haha.

THEN this morning it happened again. This time the client didnt even repair itself. I opened it up, logged in, and everything reset again. I dont wanna have to keep fixing my settings and making 7+ rune pages again.

Does anyone know whats happening or of this is happening with them? Thank you.
