Re: BF6 BSOD on Launch: EA AntiCheat Crash

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`563ee6e6 4d09c1          or      r9,r8
    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.

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

    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}

(cm edit removed mass tag)

Battlefield 6 consistently causes a Windows BSOD on launch after reinstalling EA AntiCheat / Javelin as administrator.

This is not a normal user-mode game crash. The latest minidump points to EA AntiCheat / Javelin as the faulting kernel module.

Already tried:

• Reinstalled EA AntiCheat / Javelin as administrator
• Reinstalled EA AntiCheat / Javelin multiple times before that
• Cleared EA App, Battlefield, and shader caches
• Reinstalled NVIDIA drivers
• Disabled Discord and NVIDIA overlays
• Updated motherboard BIOS
• Disabled MSIO / Asusgio2 / Asusgio3 kernel drivers
• Tested CPU ratio cap workaround
• Verified TPM and Secure Boot

The crash still reproduces.

I can provide the full minidump, full WinDbg output, msinfo32, DxDiag, and event logs privately to EA staff.

Please escalate this failure hash to the EA AntiCheat / Javelin engineering team:

Have same problems with BSOD crashes in 3rd season, idk why they cant fix it in first week *facepalm*

Happened at 3rd season for me too. First thing I tried updating the BIOS, but it didn't help (it helped some others, though, so worth trying).

didnt help me 2

Yeah I have the same issue however im on Ryzen

Tried literally everything 
Tried updating BIOS
nothing worked 
It is 100% Javelin issue
And it has been persistent for a month

It's been there since the start of Season 3 and I haven't been able to play that season at all. Crashes every time. It's definitely a Javelin issue.

I have now compared your minidump details to mine and they are exactly the same.
I cant play since late may which I believe have been an extra update, however I have been playing Golmud when it released.

Im on build 26200 and Ryzen so its not platform specific either.

I merged your thread with a larger thread with similar issues from the community.

I have a full dump, WER files, logs, DxDiag and SysInfo32 outputs all packaged, if someone wants to look at it.

XIO-X2​ Hey,

Yes. Please upload them here so that we can review them.

Thanks

EA_Shepard​ Hi,

I sent you a direct message with the link to the full package, because I don't want to post specific system details on a public thread.

Thank you for taking the time to look into this.

EA_Shepard​ Hi,

Any info on the ZIP file? I hope you understand why I can't post my full system spec on a public forum. Should I curate it and post here or was sending it in DM okay?

XIO-X2​ Hey, curate it as best you can. I completely understand not being able to, and we don't want players doing so if they are unable to.

EA_Shepard​ I'm attaching a redacted version here. I've removed the dump files and added #### over any ids or data that might be used to target the machine. Still, I've sent a full non-redacted ZIP with all the dumps to your inbox, in case you wanted to forward it to the Javelin team.

Hi EA_Shepard​ 
Has there been any update?
I've just updated to the season 4 update and nothing really changed, the issue is the same and constantly persists.
Makes me completely unable to play any games which use the same Javelin anticheat

jaChrzan​ Hey, I requested one as I haven't seen one. The last one I saw was for Nvidia players to clean install the previous drivers, and AMD users to clean install the Adrenalin drivers.

Not every crash is the same since these steps resolve some, but not others.

EA_Shepard​ Hi, I've tried again installing older nvidia driver, one from before the may update, and the issue constantly persists. Only thing I havent tried yet is clean reinstall of windows but I cannot do it right now. 
Thanks

Same for me still.

I wouldn't do a Windows reinstall. From all the dumps it's pretty clear the issue is in how their driver manages memory. It's highly unlikely that a Windows reinstall would solve this.

jaChrzan​ Yeah, I feel like a Windows install like this would not do much, honestly. It seems more geared to the drivers. This is why they set up this: Known Issue: NVIDIA GPU Driver Crashes on Certain Maps 

Having this issue as well. Tried launching three times: Got part way through the Season 6 cinematic, then BSOD. Next, got a warning that my save was corrupted or something. Seems like my settings were reverted. BSOD after messing around with the initial settings iirc. Next, updated NVidia drivers, got all the way to the main menu, went to the loadout screen, then BSOD after spending a minute or two in there.

Haven't launched the game since the first day of Season 1. One of the BugCheck events specifies eaanticheat.sys as the suspected driver.

Hardware:

Intel i7-13700K -- Updated BIOS around May 2026, so I have the stability patches. Confirmed still up to date as of today 2026-07-30.

NVidia RTX 4070Ti

32GB (2 x 16GB) DDR5-6400

Samsung 980 PRO 1TB NVMe SSD (C: drive)

Samsung 870 EVO 4TB SSD (SATA III) (game is stored on this drive)

Windows 11 Pro 64 Bit English

EA_Shepard​ Hi. Is there anything happening with this? I've now skipped two seasons of the game, because it crashes every time it is launched.
