This error might be also triggered by a 3rd party AV or an external firewall. This is happening because the AV or firewall is quarantining some files belonging to the game after a security scan. If this is the case for you, you can start by disabling the real-time protection of your antivirus. Most 3rd party antiviruses will allow you to do this directly from the tray bar icon of your AV suite.
