The Valve Anti-Cheat System (VAC) is a program that detects the installation of popular games in any format other than their intended format without using the correct product keys. VAC is used to prevent malicious users from taking advantage of workarounds in order to gain an unfair advantage while playing the game.
The VAC occasionally generates a false statement. As an example, the user may be utilizing incorrect configuration files or files that have been updated.
As a result, while playing online, it displays an Error notice.

Step 8: Keep in mind that reinstalling the game will not fix the issue, and it will continue to load with the same error. It is more effective to log in and log out than to reinstall the game. The game should be installed from scratch.
