Black Screen After Champ Select

In the recent week, currently September 2, I have had problems playing league of legends because every time i try and load into a game i get a black screen. Whenever this happens I get a notification that I have been disconnected and I need to reconnect even though my internet is fine. I have tried every possible solution I could find and nothing has worked. If somebody could provide me with a solution that would be great. Thanks Fam.
