Hardcrash/Bluescreen caused by EA Anticheat after new Patch
I previously posted about this in a thread on error 95 caused by EA Javelin Anti Cheat. However, I believe my bug could be actually unrelated as I have not encountered error 95. Sorry for slight content doubling. Maybe other people also encountered my bluescreen issue and are reassured by reading this.
This morning my game had first connection issues with an unkown error. (Probably unrelated)
Then on restart and rejoin in a Nightfall match I was thrown out of the match (maybe due to inactivity or connection - there was no info) and the game crashed without an error.
I directly restarted the game and very shortly after a text appears on my screen that my pc needs to be restarted. That was around 1:30am CET.
It triggers memory retraining with a boot for like 69s. And I can find out afterwards that I had a bluescreen. Windebug points directly to eaanticheat.sys.
Start of the windebug:
"IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an interrupt request level (IRQL) that is too high. This is usually caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace."
First mention of ea anticheat follows shortly
"Debugging Details:
------------------
*** WARNING: Unable to verify timestamp for eaanticheat.sys"
It also appears in the stack trace which I ommitted here. I'm actually unsure if it would be clever to post it publicly. However, it ends with identifying the following names. (My pc is running Win11 I don't know why windebug thinks it is win10)
"SYMBOL_NAME: eaanticheat+c4e856

Bf is the only game that has ever bluescreened or hardcrashed my current pc in general. In the past it caused 2 unrelated nvidia driver tdr crashes but that's at least partially the fault of Nvidia's drivers but partially also your game's fault as it loved/sometimes still loves to throw "directX device hung" errors that seemingly very rarely make the driver hardcrash.
I run the repair routine for the anti cheat as this was suggested somewhere else but I feel that this bug is unresolved. However, it's not easy to reproduce. I played one match on Hagental afterwards without any problems.
Maybe a prior normal game crash leaves the anti cheat in a fail state that leads to illegal memory address operations causing the bluescreen?
I feel that this is related to the bluescreen that is also reported here
https://www.reddit.com/r/Battlefield6/comments/1rzexzi/crashing_with_latest_update/
Furthermore, another user on the official discord reported a bluescreen after the new patch. So, I'm not alone in this. Also, multiple people over reddit report hardcrashes and Westie experienced one in his stream. I don't know if they had similar bluescreens, but I suspect so.
I hope you can fix this very soon. It spooked me a bit and annoyed me way more. Bf6 is unfortunately on the unstable end of my gaming experiences. The performance is stellar though. Bf2042 ran so much worse and looked worse as well.
Have a nice day!
