UE4 project editor CRASHED!

Hi, I’ve just installed UE4 but whenever I open my project, it shows crash error. Log file and crash error screenshot attached.

Please need help!

This happens to me too with 4.18 preview, but with different errors, although they are still dxgi errors. I get DXGI_ERROR_DEVICE_HUNG and DXGI_ERROR_DEVICE_REMOVED.
I updated the NVIDIA drivers today, but after the crash appeared. The only change to my system that happened before the crashes was Windows’ update to the build 15063.674.

Any solution?
