The "VAC Was Unable to Verify Your Game" error in Counter-Strike 2 (CS2) can be caused by a number of factors, including corrupt game files, interference from your antivirus or firewall, or some random software. Very recently, AMD’s Anti-Lag was causing issues with Valve Anti-Cheat (VAC) and it led to players getting banned. Valve has addressed the issue and reversed the bans but similar incidents can occur because of other software. Here is a quick rundown on how to fix the “VAC Was Unable to Verify Your Game” Error in Counter-Strike 2.
