Critical EAAC Anti-Cheat Vulnerability (China Region Exclusive)
There is a severe functional vulnerability in EAAC Anti-Cheat that affects all players in the China region: when launching any game using EAAC Anti-Cheat, a mandatory pop-up message appears stating "Anti-Cheat needs to be updated." However, even after manually downloading and reinstalling the latest version of EAAC, the issue persists. Through testing, the root cause has been confirmed: upon launching the game, the EAAC Anti-Cheat program automatically rolls back its own files to an older version, resulting in repeated update prompts and failure to access the game normally. Currently, the only temporary workaround is to disconnect from the internet during the EAAC Anti-Cheat startup loading phase to successfully enter the game. This vulnerability has impacted all games utilizing EAAC Anti-Cheat (such as the Battlefield series), severely disrupting the gaming experience. We kindly request the official team to investigate and fix this issue as soon as possible! 启动游戏后，反作弊相关文件会自动回退至7月11日版本
Battlefield 1 & V bug freezes my PC - hard reset needed - faulty anti cheat
UPDATE: I managed to get a normal crash rather than a full system freeze. Go on registry editor, at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers and make sure TdrLevel registry key is set to Decimal 3. If there is no "TdrLevel" create a new DWORD value, set Decimal and set to 3. Then restart your PC. My crash message looks like this now: DirectX Error DirectX function "GetDeviceRemovedReason" failed with DXGI_ERROR_DEVICE_HUNG. GPU: "", Driver: "25.5.1 (25.10.01.09-250425a-415182C-AMD-Software-Adrenalin-Edition)". This error is usually caused by the graphics driver crashing; try installing the latest drivers. Also, make sure you have a supported graphics card with at least 1024 MB of VRAM. This doesn't solve the issue since the game is still causing crashes but at least it solves the hard freeze. By opening Event Viewer I can see more info about the crashes: Faulting application name: bf1.exe, version: 1.0.0.0, time stamp: 0x67924d43 Faulting module name: bf1.exe, version: 1.0.0.0, time stamp: 0x67924d43 Exception code: 0x80000003 Fault offset: 0x00000000002eaedd Faulting process id: 0x0x4B20 Faulting application start time: 0x0x1DBCF6301395123 Faulting application path: D:\SteamLibrary\steamapps\common\Battlefield 1\bf1.exe Faulting module path: D:\SteamLibrary\steamapps\common\Battlefield 1\bf1.exe Report Id: 06c26cb6-f765-4768-a57c-b442d5ae6366 Faulting application name: EADesktop.exe, version: 13.468.0.5981, time stamp: 0x6827adff Faulting module name: libGLESv2.dll, version: 2.1.19909.0, time stamp: 0x63ced377 Exception code: 0xc0000409 Fault offset: 0x00000000004b7c55 Faulting process id: 0x0x17A8 Faulting application start time: 0x0x1DBCF62F3565FC5 Faulting application path: C:\Program Files\Electronic Arts\EA Desktop\EA Desktop\EADesktop.exe Faulting module path: C:\Program Files\Electronic Arts\EA Desktop\EA Desktop\libGLESv2.dll Report Id: f554f8e7-f1e1-48c4-8a62-97e481b7dd00 Faulting application name: bf1.exe, version: 1.0.0.0, time stamp: 0x67924d43 Faulting module name: KERNELBASE.dll, version: 10.0.22621.5331, time stamp: 0xe44cbdc8 Exception code: 0x887a0006 Fault offset: 0x00000000000601dc Faulting process id: 0x0x7364 Faulting application start time: 0x0x1DBCF6504D7C504 Faulting application path: D:\SteamLibrary\steamapps\common\Battlefield 1\bf1.exe Faulting module path: C:\Windows\System32\KERNELBASE.dll Report Id: 330ebf06-1e99-453a-8e99-b0fe46728003 These were generated from 2 different crashes, first 2 errors on one crash, the second on another crash. Last crash it seems kernelbase.dll crashed bf1, which still suggests the anti-cheat is at fault here. Below you have the original post with the previous edits: I am experiencing this issue on BF1. As far as I've seen across the forums, the same anti cheat system was installed on BF V as well, and plenty of similar posts across the forums for both of the games. It has to do with the new anti-cheat system. I've played for 200 hours (stopped a few months ago, before the new anti-cheat update) and when I started playing again yesterday I can get in a game, and within a few minutes to a few dozen minutes the game will literally freeze (audio continues to work for a while), i can move my mouse around on the frozen bf1 game but I am unable to do any command (alt+tab, ctrl+alt+delete, windows+tab, ctrl+shift+win+b, alt+f4 etc), literally nothing. After a little while my mouse stops working too , audio cuts off and my PC is left in a frozen state, on the last frame of the battlefield game right before the freeze. This has to do with the crap anti cheat system that works at a kernel level. Perhaps it has to do with certain CPU architectures and it not being optimized for all. My system specs are: AMD Ryzen 9 7950X AMD 7900 XTX G.Skill 64 GB RAM 6000Mhz BF1 is the only game that does this. I've also noticed I am having stutters in the game, especially the minutes before having a crash. I tried every type of fix like setting my power plan to balanced (popular fix online - doing this allowed my to have my longest session of like 20-30 minutes i think, but still crashed my PC), updating the anti cheat system from its tool .exe, removing the anti cheat files and verifying integrity on steam, trying to run on compatibility mode, running the CPU on one CCD, etc) and no luck. It's clearly the problem is from the new update and since the new update introduced a new anti cheat system and the crash seems to be a kernel-level type of crash since it requires a hard reset of the whole PC, I think we have the answer -> faulty anti cheat system, possibly on the ryzen architecture CPUs, mine being AM5. EA, I am tired of trying fixes and I will stop trying fixes since I have hard rebooted my PC at least 5 times trying to fix your faulty update. Get this sorted ASAP. EDIT: Based on the comments, it looks like there are plenty others with Intel PCs that have the same problems as well. It seems that it happens on both Intel and AMD CPUs as well as both NVIDIA and AMD GPUs. This enforces the idea that it is the anti-cheat that is causing the crash but it widens the search for the problem within the anti-cheat since it's no longer AM4/AM5 only. Harder for the devs, but at least we know it's not our PCs/drivers. The behavior seems to be a bit different depending on each case: some people have the same symptoms as me, others nearly the same but it ends with a BSOD, others have a freeze for a few seconds but PC recovers rather than crashing. EDIT 2: It seems that the anti-cheat is causing the GPU drivers to hard-crash at the kernel level therefore freezing the PC. Looks like it happens on a very different mix of platforms, different amd&intel&nvidia combos. If you have the same problem try stating what apps u have open as well, the ones running in the background too. Maybe it's an overlay issue or idk...
