When I was visualizing on Windows, the above problem appeared, how should I solve it?

This seems to be a problem with the OpenGL context creation on Windows; not sure how you can resolve this as it seems like a very specific problem with your system. (Maybe you have to install OpenGL drivers? But I'm not a Windows person.)
