Good afternoon, there was an error when entering into your project, when you click ok, the engine closes. Before that, there was no such error, I have a GTX 1060 graphics card.
Rename your config folder temporarly - I guess the problem will go away. if so you need to find the config setting which switches to the not by your card supported shader feature. have you done any UE updates? Have a look at the log file in project folder
