Unable to build to desktop

i have been trying to build the cesium scene through unity and had to update recently to the latest cesium package in order to access the photorealistic 3D tiles.
However, I keep getting all these errors when I try to build, any suggestions?

Those errors don’t look directly related to Cesium for Unity. If you’re using Google’s AR Geospatial Creator, I would try and ask them for support instead.
