If Battlefield 6 throws startup error 0xc0000906, the fastest fixes are usually these: change Windows Exploit Protection settings for the Battlefield 6 and EA AntiCheat executables, verify the game files, and relaunch the EA app as administrator.

What Battlefield 6 Error 0xc0000906 Usually Means

Battlefield 6 is failing before launch because Windows cannot run one of the needed executable files properly. That can happen when:

• Windows security blocks the game executable

• Antivirus software sandboxes or quarantines a file

• Game files are corrupted or incomplete

  

• EA AntiCheat fails during startup

• DirectX or Windows system files are damaged

The files most commonly tied to this kind of fix are:

• bf6.exe

• BF6.EXE

• bf6event.exe

• EAAntiCheat.GameServiceLauncher.exe

Common Triggers Behind the Error

Windows Exploit Protection

This is the most repeated player fix for Battlefield 6 launch failures related to this error. Several players report that adding the Battlefield 6 executable and EA AntiCheat-related files to Exploit Protection and turning the listed overrides off lets the game launch normally.

That does not mean EA has officially confirmed Exploit Protection as the root cause. It does mean this is one of the strongest community-backed fixes right now.

Antivirus or AV Sandboxing

Some 0xc0000906 cases happen when antivirus software isolates or blocks executable files. If your antivirus recently updated, or you use aggressive real-time protection, it may be interfering with Battlefield 6 or EA AntiCheat.

Corrupted or Missing Game Files

If the launcher shows a repair prompt or the game suddenly stopped launching after an update, file corruption is a likely cause. Verifying or repairing the install is one of the safest first steps.

EA AntiCheat Conflicts

Battlefield 6 startup can fail if EA AntiCheat did not install correctly, broke after an update, or is being blocked during launch.

DirectX or Windows System File Issues

This is lower priority than Exploit Protection and file verification, but still worth checking if the main fixes do not work. DirectX problems or damaged Windows files can stop games from opening.

How to Fix Battlefield 6 Startup Error 0xc0000906

Follow these steps in order.

1) Adjust Windows Exploit Protection for Battlefield 6 and EA AntiCheat

This is the main fix to try first.

1. Open Windows search and type Exploit Protection.

2. Open Exploit protection.

3. Go to Program settings.

4. Add these files one by one if they are present in your install folders:

   • bf6.exe

   • BF6.EXE

   • bf6event.exe

   • EAAntiCheat.GameServiceLauncher.exe

5. For each added file, enable Override system settings and set these to Off:

   • Control flow guard (CFG)

   • Data Execution Prevention (DEP)

   • Force randomization for images (Mandatory ASLR)

   • Randomize memory allocations (Bottom-up ASLR)

   • Validate exception chains (SEHOP)

   • Validate heap integrity

     

6. Apply the changes.

7. Fully close Battlefield 6, Steam, Epic, and the EA app.

8. Relaunch and test again.

If you only want to start with one file, begin with bf6.exe, then add the AntiCheat files if the error persists.

2) Verify or Repair the Game Files

If a file is missing, altered, or broken, repair the install before doing anything more invasive.

Steam

1. Open Steam.

2. Right-click Battlefield 6.

3. Open Properties.

4. Go to Installed Files.

5. Click Verify integrity of game files.

EA App

1. Open the EA app.

2. Find Battlefield 6 in your library.

3. Open the game menu.

4. Use the Repair option.

Epic Games

1. Open Epic Games Launcher.

2. Find Battlefield 6 in your library.

3. Open the game options.

4. Use Verify.

Even if you bought the game through Steam or Epic, Battlefield 6 still relies on the EA app for launch.

3) Run the EA App as Administrator

This matters even if you own the game on Steam or Epic.

1. Close the EA app completely.

2. Right-click the EA app.

3. Choose Run as administrator.

4. Then launch Battlefield 6 again from your normal launcher.

This can help if startup is failing during anti-cheat checks or EA app handoff.

4) Reinstall EA AntiCheat

This is a strong secondary fix. Some players report that uninstalling and reinstalling EA AntiCheat cleared the launch problem.

Recommended approach:

1. Close the game and all launchers.

2. Uninstall EA AntiCheat from Windows if it appears in your installed apps or through the game’s anti-cheat installer tools.

3. Launch Battlefield 6 again so the anti-cheat component can reinstall.

4. If prompted, approve the reinstall and restart the PC afterward.

If the game still fails, repeat the Exploit Protection check and make sure EAAntiCheat.GameServiceLauncher.exe and bf6event.exe were included.

5) Update DirectX and Restart the PC

DirectX issues are a lower-priority cause here, but still worth clearing out.

• Make sure your DirectX components are current

• Install any pending Windows updates tied to gaming runtimes

• Restart the PC fully before testing again

A restart is also worth doing after file repair, anti-cheat reinstall, or security-setting changes.

6) Test Antivirus Interference Safely

If the error started after a security update, antivirus interference is possible.

Safe way to test it:

1. Disconnect from unnecessary background apps.

2. Temporarily disable third-party antivirus protection for a short test.

3. Launch Battlefield 6.

4. Re-enable protection immediately after the test.

If the game launches only when antivirus is off, add Battlefield 6 and EA AntiCheat to your antivirus exclusions instead of leaving protection disabled.

7) Run SFC and DISM if Windows Files May Be Damaged

If the problem appeared after a crash, interrupted update, or wider .exe problems on your PC, check Windows system files.

Open Command Prompt as administrator, then run:

sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth

Restart after both scans finish, then try launching the game again.

Launcher-Specific Notes

Steam

Use Steam file verification first, but do not stop there. Battlefield 6 still passes through the EA app, so you should also run the EA app as administrator.

EA App

If you launch directly through EA, use Repair first, then test admin launch, then reinstall EA AntiCheat.

Epic Games

Verify from Epic, but remember the game still depends on the EA app during launch. If Epic verification completes and the game still fails, move straight to EA app admin mode and anti-cheat troubleshooting.
