A genome build is the version of the human reference sequence coordinates are measured against; mixing GRCh38 and the older hg19 puts variants at the wrong positions.
A reference genome is an assembly representing an organism's complete genetic sequence as a continuous string, accompanied by annotation (Wikipedia). GRCh38 (hg38), released in 2013, is the current human reference; GRCh37 (hg19) preceded it and much legacy TCGA data was aligned to it before the GDC re-harmonised everything to GRCh38. Coordinates differ between builds, so files must be lifted over or re-aligned, and the build is a mandatory provenance field.
