The PC is quite new i have updated and installed all drivers etc but when i'm in fortnite and i'm switching to spotify shortly i get black screen and the game crashed but why fxck i just do not check it

component

GPU: GeForce RTX 2070 SUPER Ex

CPU: AMD RYZEN 5 3600

Mainboard: B450 per vdh max

512 gb ssd

1000gb hdd

500 watt power supply

Apart from the fact that the hardware is too bad for such a bad game: It could be due to DirectX. You should also check the Windows WDDM drivers.
