it has been reported before, that when a pixel was 0 before the calculation of textures, it can lead to NaN values in the textures as well. Please go through all input rasters and make sure that none of them has a NoData value applied in the properties. Also, make sure to save the changes (File > Save Product) afterwards. If only one raster contains a NaN pixel, the result will be blank here, as in your case.
