How to Fix Chivalry 2 Error Code 30005? Anti-Cheat Troubleshooting

You open Chivalry 2, click the play button, and the game suddenly refuses to launch. Instead, a message appears showing error code 30005. The game closes before reaching the main menu. That moment can feel frustrating, especially when you want to jump into multiplayer battles.

This error usually happens when the Easy Anti-Cheat system fails to start properly during game launch. The anti-cheat service must run before the game connects to online servers. If the system cannot load the service, the game stops launching. In this guide you will learn what Chivalry 2 launch error 30005 means, why it happens, and several ways to fix it so the game starts normally.

What Is Chivalry 2 Launch Error 30005?

Error 30005 in Chivalry 2 is linked to the Easy Anti-Cheat (EAC) system, which protects the game from cheating software. Easy Anti-Cheat runs before the game loads and checks the system for suspicious programs or modified files. If the service cannot start or communicate with the game properly, the launch process stops. This often happens when the Easy Anti-Cheat installation becomes corrupted or when system security software blocks the service.

The error may also appear if certain game files are missing or if Windows permissions prevent the anti-cheat service from running. Because multiplayer games rely heavily on anti-cheat systems for fair gameplay, the game cannot start unless the anti-cheat service loads successfully.

Players usually see this error right after clicking Play in Steam or Epic Games Launcher. The Easy Anti-Cheat window may appear briefly, and then the game closes before reaching the title screen.

Common Causes of Chivalry 2 Launch Error 30005

This launch error normally indicates that the anti-cheat service cannot initialize correctly.

Common causes include:
