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.
