Principled BSDF It does not work

Again I, lol. Well, experimenting even more with the Eevee system. I realized that the lights were not the ones that did not work. What does not work well is Principled BSDF ni el Glossy. From there on out everything works. The Diffuse Shader, Emission, Glass, until Refractión. Will I have it misconfigured? Whatever At least with that I can already do some things in Eevee.
