Can't play League for more than 4 games average

After I quit the game for a while and go back on(for example a day later) the screen is stuck at the League start logo and doesn't load. After forcing it to stop working I need to reupdate the game so it says:“We have restored this installation to an older version...“ I don't have enough time to do this like every day and I don't know how to fix it. Btw I already tried setting my date and time a day and hour back and tried starting it through the patcher... Ty for any help
