Battlefield 6 anti-cheat errors, especially related to the EA Javelin AntiCheat system, are common at launch. To fix it, Close Battlefield 6 and the EA App entirely, restart the PC, then try running both as administrator to ensure anticheat privileges are granted.
⚙ What’s the Situation
-
Battlefield 6 uses a kernel‑level anti‐cheat system called Javelin, which requires Secure Boot and TPM 2.0 to be enabled on your PC.
-
Even if Secure Boot is “enabled” in BIOS, sometimes the system still shows Secure Boot as disabled or inactive — often because:
-
The system disk is still in MBR partition style (not GPT)
-
Compatibility Support Module (CSM) is turned on
-
Secure Boot mode is in “Custom” instead of “Standard” / using factory keys, or the Secure Boot keys are missing or not recognized.
-
-
Conflicts with other anti‑cheat / kernel drivers or software (like Valorant / Vanguard) are reported. If another anti‑cheat is still loaded or running, it can prevent Battlefield 6’s anti‑cheat from initializing correctly.
-
Some users report crashing at splash screen, game closing silently, or anti‑cheat services failing to start even though the service is listed.

🔧 What You Can Do: Fixes to Try
Here are steps that have worked for many users; try them in order and check after each change.
Step |
What to Check / Do |
|---|---|
| 1. Confirm Secure Boot & UEFI Settings | – Enter BIOS/UEFI → ensure Secure Boot is enabled and active. – Make sure BIOS mode is UEFI, not Legacy. – Disable CSM (Compatibility Support Module). – If Secure Boot is in “Custom” mode or Secure Boot state seems off, consider restoring factory keys or setting mode to “Standard / OEM / Factory Key” mode. |
| 2. Check TPM and Disk Partition Style | – Ensure TPM 2.0 (or fTPM) is enabled in BIOS. – Check Windows’s disk partition style: if it’s MBR, convert to GPT using Windows tool (MBR2GPT) or reinstall with GPT. |
| 3. Restore Secure Boot Keys (if needed) | If Secure Boot reports that keys are missing or invalid, restore the default/factory keys. This is under Secure Boot → Key Management in BIOS on many boards. |
| 4. Update BIOS / Firmware | Some motherboard firmware updates fix Secure Boot issues or driver conflicts. Make sure your BIOS/UEFI is the latest version. |
| 5. Close Conflicting Software | – Ensure no other anti‑cheats (like Vanguard) or conflicting kernel‑driver software are running. – Completely close their services or uninstall if needed. |
| 6. Repair/Reinstall EA Anti‑Cheat / Javelin | – Uninstall EA Anti‑Cheat service manually, then let the game / launcher reinstall it. – Use administrative privileges when launching game or EA app. |
| 7. Run as Administrator | Right‑click on EA App (or game launcher) → Run as Admin. Sometimes ensures the anti‑cheat service loads properly. |
| 8. Remove Problematic Drivers/Apps | Some users reported that background software like “Gigabyte App Center” caused the anti‑cheat service to crash. Uninstall or disable such apps. |
Last Resort Solutions
-
Reset Network Settings: Flush DNS and reset TCP/IP in Command Prompt to address networking issues that can block anticheat.
-
Reinstall Battlefield 6: Uninstall the game and manually delete game folders before reinstalling—the nuclear option if all else fails.
Applying these fixes step-by-step resolves most Battlefield 6 anti-cheat errors and lets the game launch normally.
