What are you trying to do? I don't see the point in a shiny program that doesn't even create a window. There's likely a loop internally in the driver that's handling processing of events from the OS and since you're never creating a window, it's never exiting (this is just a guess, I haven't looked at the code lately.)
Have you looked at the samples in https://github.com/golang/exp/tree/master/shiny/example? They're likely a better place to start.
