Crashing and lagging in loadingscreens

My game lag and crash in loading screen. I can only leave game and I have leaver penalty, because game crash in loading screen when I’m going to game or somebody kill’s me in game. I have Intel i7-8700K processor and Nvidia 1060 GPU. Lag and crashing is only in Overwatch. My game name is Seedim #21379. I have 16gb ram. Mu computer isn’t problem. Problem is in game. And now my game don’t launch, but battle.net says it’s launched. My game launch three minutes after I launch it and then it crash. I try to make web ticket but it doesn’t works.
