BF6 Crashing to BSOD on Launch

Battlefield 6 has BSOD'd on launch every attempt since May 22, 2026 — one day after the May 21 Javelin anti-cheat depot update. No software, hardware, BIOS, or driver changes were made on my end befo...

I had to update my BIOS, and it fixed it.
For Intel 13th and 14th Gen systems on the MSI B760 GAMING PLUS WIFI, an outdated BIOS causes severe stability issues when launching games with kernel-level anti-cheat like Battlefield 6. The root cause is a factory microcode bug that forces incorrect, elevated CPU voltages, causing the processor to deliver corrupt data under the intense low-level stress of the anti-cheat software, resulting in instant crashes.
Updating to the latest BIOS applies the essential Intel microcode patches (like 0x12F) that enforce safe voltage limits and completely resolve those launch failures.
Downloaded the update to USB, updated, BF6 works

Battlefield 6 is consistently causing a Windows BSOD during launch / shortly after launch.

This is not a normal user-mode Battlefield crash. It is a Windows kernel bugcheck, and WinDbg identifies EA AntiCheat / Javelin as the faulting module.

WinDbg summary from C:\Windows\Minidump:

PAGE_FAULT_IN_NONPAGED_AREA (50)

Arguments:

Arg1: ffffe40011bbd000, memory referenced

Arg2: 0000000000000000, read access

Arg3: fffff8036cb007f6, instruction address that referenced bad memory

Arg4: 0000000000000000

Key WinDbg fields:

PROCESS_NAME: bf6.exe

MODULE_NAME: eaanticheat

IMAGE_NAME: eaanticheat.sys

SYMBOL_NAME: eaanticheat+1b407f6

FAILURE_BUCKET_ID: AV_eaanticheat!unknown_function

FAILURE_ID_HASH: {d544cf09-4735-e698-77c3-5df5924e5448}

Faulting instruction:

eaanticheat+1b407f6:

mov r9d,dword ptr [rbx+rax+8]

Relevant stack excerpt:

eaanticheat+0x1b407f6

System:

Windows 11 10.0.26200 Build 26200

CPU: Intel Core i9-12900KF

GPU: NVIDIA RTX 3080

RAM: 64 GB

Motherboard: Gigabyte B660M DS3H DDR4

Secure Boot: On

TPM: Present

VBS: Running

Credential Guard: Running

Hyper-V / hypervisor: Present

NVIDIA driver at time of dump:

32.0.16.1047

What I have already tried:

Reinstalled EA AntiCheat / Javelin multiple times
Cleared EA App cache
Cleared Battlefield cache
Cleared shader caches
Reinstalled NVIDIA drivers
Disabled Discord overlay
Disabled NVIDIA overlay
Tried different monitor configurations
Updated motherboard BIOS
Disabled MSIO / Asusgio2 / Asusgio3 kernel drivers
Ran extended memory diagnostics
Verified Secure Boot and TPM are enabled/present

The crash still occurs, even after the last Battlefield update. This has been happening for a month now.

I am not asking for generic advice such as reinstalling Windows, reinstalling the game, checking Secure Boot, checking TPM, or scanning for malware. The dump points to a kernel-mode crash in eaanticheat.sys. This should be escalated to the EA AntiCheat / Javelin team.

Questions:

1. Is FAILURE_ID_HASH {d544cf09-4735-e698-77c3-5df5924e5448} already known internally?

3. Is there a known workaround other than disabling core Windows virtualization/security features?

4. Can EA provide a fixed EA AntiCheat / Javelin build or acknowledge this crash signature?

I can provide the minidump, full WinDbg !analyze -v output, msinfo32 export, DxDiag, and any requested Code Integrity / Event Viewer logs privately to EA staff.

If other players are seeing a BSOD with eaanticheat.sys and the same failure hash, please reply with your Windows build, CPU, GPU, NVIDIA/AMD driver version, and whether Hyper-V/VBS is active.

Apparently, [removed] doesn't care about this issue. Battlefield 2042 crashes with the same errors, so I basically have two unplayable games on my PC which cannot be refunded.

Here's the info from the last crash (I can provide the full dump file, if necessary, but this should be enough to figure out the issue):

Faulting instruction
--------------------
WinDbg command:
    u fffff805563ee6de L20

Faulting instruction:
    eaanticheat+0x188e6de:
    fffff805`563ee6de 448b4c0308  mov r9d,dword ptr [rbx+rax+8]

Surrounding disassembly:
    fffff805`563ee6d7 4c8b0403        mov     r8,qword ptr [rbx+rax]
    fffff805`563ee6db 4931c8          xor     r8,rcx
    fffff805`563ee6de 448b4c0308      mov     r9d,dword ptr [rbx+rax+8]
    fffff805`563ee6e3 4131d1          xor     r9d,edx

    fffff805`563ee6e9 0f8544ffffff    jne     eaanticheat+0x188e633

Faulting memory address / PTE
-----------------------------
WinDbg command:
    !pte ffffe480cb703000

Result:
    VA ffffe480cb703000

    PTE contains:
        00007A7000000000

    Status:
        not valid
        Page has been freed

This is consistent with a read from invalid/freed memory at the faulting instruction inside eaanticheat.sys.

Relevant loaded-driver context
------------------------------
The faulting stack shown above is nt -> page fault handling -> eaanticheat.sys. The stack does not show NVIDIA, Defender, Code Integrity, NordVPN, WireGuard, OpenVPN, ASUS/MSIO, or other third-party drivers as the executing faulting frame.

Some other loaded modules observed in the dump, for completeness:

    nvlddmkm.sys       loaded; not present in the faulting stack
    CI.dll             loaded; not present in the faulting stack
    WdFilter.sys       loaded; not present in the faulting stack
    WdNisDrv.sys       loaded; not present in the faulting stack
    NDivert.sys        loaded; not present in the faulting stack
    nordlwf.sys        loaded; not present in the faulting stack
    tapnordvpn.sys     loaded; not present in the faulting stack
    wireguard.sys      loaded; not present in the faulting stack
    ovpn-dco.sys       loaded; not present in the faulting stack
    MsIo64.sys         loaded; not present in the faulting stack
    AsIO2.sys          loaded; not present in the faulting stack
    AsIO3.sys          loaded; not present in the faulting stack

Notes
-----
1. The crash still occurs after reinstalling EA AntiCheat / Javelin as administrator.
2. The active process at the crash is bf6.exe.
3. The faulting instruction pointer is inside eaanticheat.sys.
4. The access type is read.
5. The referenced page is invalid and marked as freed by !pte.
6. The failure hash is stable:
       {d544cf09-4735-e698-77c3-5df5924e5448}
