You have null variables - check your code.

It’s probably not finding a valid video card (D3D11CreateDevice() fails).

This is a forum for people developing with UE4, not playing games. Please direct your questions to the right audience.

Thank you very much for your help.
I started the game with the built in graphic equipment.
