Runs minimized to tray (Call of Duty: Warzone)

Installed, downloaded (88гб when the speed of the Internet in 35мбит else is perversion)
Start the game, an icon appears in the system tray that the game is running, headphones in music playing, probably from the initial menu. But can not be switched to it, neither the mouse nor with ALT+TAB
The cursor will disappear and everything, no picture..

Demolished, reinstalled - to no purpose
All drivers updated, all libraries and so on too
