Exit CS2 and Steam, remove software that modifies the game, then restart the PC. In Steam Library, open Counter-Strike 2 > Properties > Installed Files > Verify integrity of game files, clear unsupported Launch Options, and launch normally through Steam. This verification error is not by itself proof of a VAC ban.
Exit CS2 and Steam. Remove custom textures, skin changers, injectors, or other software that modifies the game, then restart Windows. Do not disable Windows security, end unknown system processes, or download replacement DLL files.

Verify the CS2 files
Open Steam Library, right-click Counter-Strike 2, and select Properties > Installed Files > Verify integrity of game files. Wait for Steam to complete the check and any download before starting the game.
3
Clear unsupported launch options
In Counter-Strike 2 Properties, open General and remove copied or unsupported text from Launch Options. Close Properties and launch CS2 normally through Steam rather than a modified shortcut or executable.
4
Verify access to a secure session
Join an official secure matchmaking or practice session. Success means the game connects without the VAC verification message. If the message returns, note the exact text and stop repeating file verification.
5
Use Valve's advanced recovery only if needed
Open Steam's Disconnected by VAC support page and follow its current advanced recovery branch, including Steam Service repair, only when the basic steps above fail. Use the commands exactly as Valve publishes them and contact Steam Support if the documented repair does not restore secure access.
If it does not work
If Steam reacquires files, restart Steam after the download finishes and test once before restoring any optional modifier.
If the account shows an actual VAC ban notice rather than a session-verification error, this tutorial cannot remove it. Use the account notice and Steam Support's VAC information.
If secure access works until one optional tool returns, remove that tool and verify files again. Do not create broad firewall exclusions or run CS2 permanently as administrator.
ⓘ Sources and verification
Checked against official documentation on . Scope: Windows PC.
Source-checked against Steam's current VAC, file-verification, and launch-options guidance. The advanced Steam Service repair remains an official escalation, not a first step.
