Match history bug

Hi. I have a problem wich many people that i know dont seem to have. From the date 30/07/2019 my match history is locked(i cant see any previous matches from the date i typed earlier to this day) Not ranked games not normal games nothing. And this never happened to me before and i cant find anything like this on youtube/google. I tried reinstalling league i even tried going to different sites and some of them show the games some of them dont and this includes official match history page from league. Pls help because im scared of people saying that i somehow discovered a lp hack wich gives me lp without playin ranked games. And i dont want to get banned since i have no official proof of this matches =[[[
