The only solution that helped me was to switch off Freesync. I was able to reproduce the error very well. With every new game, the black screen with sound came back - until I deactivated AMD Freesync in the Adrenalin Driver (Home, Game, Game Settings, Freesync off). It is an annoying problem, as the setting s for Freesync can be found everywhere. Below Gaming -> Display, Global Performance Settings, in the game itself under Graphic Options .... and finally also on the display itself.
