For some, this error occurs due to the security programs installed on their computer. There are some features of the antivirus that can prevent the program to run properly. If this is the case, try disabling your antivirus temporarily but remember that this step will make your computer prone to viruses. For others, this issue is due to Firewall. To resolve this, you may need to disable your Firewall while you are playing the game or just allow the game to access Internet or run the game in offline mode.

If none works, you can go to Steam Powered official page and report the error you are encountering.
