BF6 Crashing whole PC, what is this error code?

Hi, I need a dev to let me know and many others what this means? I've tried everything, the beta played perfectly but since the launch of BF6 I've had nothing but dramas. First I purchased it on EA ...

I found my fix 100%. it's a BIOS issue that breaks the secure boot encryption key, that in game will block the game or anything on the PC from accessing the memory.
If a BIOS flash doesn't fix it, 100% guaranteed fix is removing your CPU and then re installing into the socket. The secure boot keys store something in the CPU somehow or in the chipset and only removing the CPU will fix it.
I even believe I know how it's caused or at least how I caused it.
I can enable XMP but only up to 2700Mhz from 2100Mhz (no longer can reach 3200Mhz) since the bios security fixes.
It worked fine but for at least a week or two and the issue came back a second time when I put my PC to sleep and after waking it up I played the game, the XMP has to be applied at boot, so there is a conflict in the memory addresses or something like that, Once you do this it's broken and will constantly crash, barely able to play. Removing the CPU will fix it even without resetting the bios.
Now the game never crashes and I'm running my 10700k at 5Gmz just now without XMP..
EDIT: Also remove your memory as sometimes it needs both CPU and memory so better to be safe.
EDIT 2, 30th April 2026: This time removing CPU and memory didn't fix it, so I tried one more time but this time removing all three, CPU, Memory and GPU and clearing CMOS while all the gear was out.
Before doing this I cleared the security keys and restored defaults in BIOS twice I think it needs two restarts not just one, like when clearing CMOS or flashing the BIOS requires, on the second it even shows up on display 1 not 2. This happens every time I restore defaults twice in a row.
This finally fixed it I couldn't even get into the game, clearing keys and flashing does nothing and CMOS does nothing, removing the hardware seems to trick secure boot it's a new PC or something, I have no idea what triggers this issue but it's happening more often in season 2 BF6.

Hello. I’m having a similar problem. I noticed in the Event Viewer that the same error appeared: "Secure Boot CA/keys need to be updated." After looking into it a bit more and resetting the keys in the BIOS, I realized that every time I started the game, that error would show up right afterward — and then, after about 2 hours of playing, the game would crash with an access violation.

you can ignore that that turns out is always there, I found my solution. It's corrupted BIOS/Secure boot keys. I had to remove my CPU to fix it, done it twice and fixed it both times, now it never ever crashes. The game is stable if you have it all good on your end in my opinion.

First try switching Ram sticks around. Another time it was caused by recording software like OBS replay to ram. Memory is very locked down in secure boot and some thing triggered it. This time CPU removal didn’t fix it but swapping memory sticks around did.

when the issue was XMP removing and swapping the RAM didn’t fix this, neither did removing rhr battery or resetting CMOS or flashing BIOS. It was due to waking PC from sleep when I had XMP enabled. The PC can only enable XMP on full reboot, so putting it to sleep reset the memory to default when it woke the PC. This caused a conflict and once this happens ypu have to fix it or else it will keep happening. In that situation the only thing that fixed it was removing the CPU, might as well switch the RAM as well as I think I did that as well but I tried switching the RAM on its own when I removed the battery but that did nothing till I removed the CPU.

Yeah don't worry about that, it's not the cause of the issue. You can update it in Powershell as admin if you follow the link in that event viewer at the bottom from Microsoft. You have to enter a few commands one at a time.
