SU-PQR1603 installing prerequisites error

Sorry for my english T_T
While i was searching to install prerequisites of Epic Games Launches, it always gives me "SU-PQR1603"error . I found a fix while editing target of shortcut i can skip this part but then, games like Fortnite or the same Unreal Engine 4.18.3 will crashsafter starting. i reinstalled the launcher but with the same problem. Also i downloaded all the software like virtual basic required by an Epic Games Support post. Someone can tell me how to do? Before the lastest update i was able to run all games without prerequisites but now i can’t. Why?

I’m having the same problem. When I use the shortcut workaround I can’t play Fortnite. Without it I can’t launch Epic Games launcher to play Fortnite… Please help, the game is unplayable and i purchased a battle pass…
