Problem with quixel bridge materials

Hello! I have a problem trying to import materials from quixel bridge to UE version 4.27. In version 4.26 it works fine, and until a while ago it also did in 4.27. But now, every time I import a material, the textures are imported correctly, but the material itself turns black. And instead of showing the parameters of megascans, when you open the material editor, what you see in the photo appears. I already tried to reinstall quixel bridge, as well as version 4.27 of the engine.
