hello, thanks for your answer.

you mean this?

I am on a w10 laptop with directx 12 already installed
and this Directx 2010 June goes only till w7

I realised that the problem comes with Directx 12 crashing:

[2019.07.03-21.35.12:761][145]LogD3D12RHI: Error: Driver crashed while creating texture: 1024x1024x192 DXGI_FORMAT_R16G16B16A16_FLOAT(0x0000000a) with 11 mips

If I change the default RHI to Directx 11, the project opens again
But this means I can not use raytracing

Any advise to be able to open the project again with directx 12 enabled?

I am facing same error when opening map(level).

I use migrate tool and transfer that map(level) to new project and it works for me.
