Re-download CS:GO .VPK files
The error is due to a possible fault in you .VPK files in the system. It is better to delete all the VPK files and download them again from steam integrity verification. This sets filters out any VPK file with error and you can then install new ones. To delete the files, go to your CS:GO installed directory. Then look for VPK files and delete them all.
