Hi,  
This is a hardware error your PC graphics card need to have its drivers updated to support DirectX 12 Shaders 6 (SM6).

For Nvidia Graphics drivers use

minimum specification  
[Hardware and Software Specifications | Epic Developer Community (epicgames.com)](https://dev.epicgames.com/documentation/en-us/unreal-engine/hardware-and-software-specifications-for-unreal-engine#requirementsforue5renderingfeatures)

```auto
Software Ray Tracing:

Video cards using DirectX 11 with support for Shader Model 5
Hardware Ray Tracing:

Windows 10 build 1909.1350 and newer with DirectX 12 support
One of the following graphics cards:
NVIDIA RTX-2000 series or newer
