How to Fix Battlefield 6 Anti Cheat Error – 7 Useful Fixes

For a general EA Javelin error, try the fixes below in order. If the message names specific software, a driver, or Secure Boot, go directly to the matching fix.

Fix 1. Fully Restart BF6, the EA App, and Your PC

A temporary EA Javelin or launcher issue may prevent Battlefield 6 from starting correctly. Fully close BF6 and the EA app, then restart your PC to clear stalled processes and clear temporary launcher or anti-cheat states.

Fix 2. Run the EA App as Administrator and Launch BF6 from It

If EA Javelin shows Error 94, it may be unable to start Battlefield 6 or locate the game’s installation folder. EA recommends relaunching the EA app with administrator privileges and starting BF6 directly from it. Follow the steps below.

Step 3. Launch Battlefield 6 directly from the EA app, even if you purchased it through Steam or the Epic Games Store.

For Error #119, use the driver name shown in the message to identify its associated software. If updating does not restore compatibility, disable or uninstall that software according to the manufacturer’s instructions, then restart Battlefield 6.

Fix 4. Reinstall EA Javelin Anticheat
