Ok so, as of today, my game during Unrated/Comp/Shooting range randomly freezes up as if i had disconnected, but i can hear game sounds, type and talk. After a while my screen goes black with the sound as if i have left the game back to main screen, but the screen stays black. To fix it i have to restart my game.

I have never experienced this but it started happening today right as i setup my new 144 Hz monitor. I don't know if these 2 are related, but has anybody else faced this issue??
