Crashing on launch and low fps

I have just installed UE4 and when i create a proyect it crashes when the editor loads, other times it loads successfully but the editor lags a lot. I tried dubugging UE4 in VS17 and this error is displayed by VS17 debugger, (i think this error is what causes these crashes):

Exception thrown at 0x00007FFF4019AEC9 (d3d11.dll) in UE4Editor.exe: 0xC0000005: Access violation reading location 0x0000024A00000000.
The subprocess is: nvwgf2um.dll

I tried setting target parameters to -DX12 and it didnt worked.

All video drivers are up to date.
