League client is overall bad

Hello i have been getting disconnect bugs every day in league and it's making me lose games i get into the game and its just randomly disconnects me and first of all its not a internet problem since at the same time i disconnect im talking on discord with my friends and everything is fine i can open up anything. And even if i disconnect and try to reconnect its just a black screen and it says unable to reconnect try again ? with the options yes or cancel. I literally have to restart my whole pc to open up the game and get into the game and play by the time im in im 4 levels down and i died because of the disconnect and if my team remakes i get a leave buster and a game loss please someone help me to troubleshoot this is it because of discord is it because league client is just straight up bad or what pls help this has lost me so many games it unbelievable. Also there is no right board to put this on so im gonna put it on bug report don't flame me on that
