Oh, the dreaded VAC error! Here's a quick fix rundown: First, try restarting your PC. If that doesn’t work, verify the integrity of game files in Steam. Right-click CS:GO in your Steam library, go to 'Properties,' then 'Local Files,' and click 'Verify integrity of game files.' Sometimes, disabling background apps that might interfere with Steam, like antivirus software, helps too. Lastly, make sure your Steam client is up to date. Good luck!

Firewall settings, folks! Sometimes your firewall straight up blocks parts of Steam or CS:GO without telling you. Give it a check.
