Verify your CS2 game files
The first step to fixing the CS2 Valve Anti-Cheat timed out error is to quit the game and verify the game files. Follow the steps below to do this:
- Head to the Properties and go down to the Installed Files tab.
- Press the button that says “Verify integrity of game files.”
- Wait for it to complete automatically.
- If the process detects any issues with your CS2 installation, it will automatically redownload the correct files.
- Wait for the files to redownload.
Restart your PC before launching CS2
Once you’ve verified the integrity of your game files, it’s time to restart your PC. Think of it like a flushing out of whatever was causing the CS2 Valve Anti-Cheat timed out error in the first place.
After a clean restart, you’re all good to launch CS2 again.
Close any external programs besides Steam and CS2
After your PC has restarted and you’re ready to jump back into the game, make sure Steam and Counter-Strike 2 are the only programs launched on your PC. The reason for this is that it’s known that applications such as Discord and its overlays can cause the CS2 Valve Anti-Cheat timed out error to rear its head.
With a fully-verified game and a clean reboot and launch of the game, you should be all set to play CS2 again.
