BF6 BSOD on Launch

(Solved for my case, check my latest reply)*****

I have this as well.. BSOD. I played it 3 ish weeks ago. after months of waiting for updates to make it actually Battlefield. It finally looks decent to play..

Updated it, now it BSOD for 3 days. Can't fix it. Requested a refund in steam. Cbf with it(refund denied lol. 200hrs)

I uninstalled and then ran the installer with admin privileges. It still crashes.

Here's some of the WinDbg analysis output:

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.

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}
