PC freezing after 10 minutes of playing since 4/16

Subject: Potential fix for BF6 hard freeze (Inter-operation between Windows Update KB5083769 and EAAC)

Hi, since your hardware is top-tier (Ryzen 9950X3D + RTX 5080), this freeze is likely not a hardware failure, but a conflict between the latest Windows Security updates and EA Anti-Cheat (EAAC).

When Windows updates its kernel security (like the recent KB patches), it often sees the "monitoring" behavior of EAAC as a threat and locks the system to protect itself, causing a hard freeze.

Please try these 3 steps to lower the "security wall" for BF6 specifically. These are the least time-consuming methods to diagnose the issue:

1. Disable "Core Isolation" (The most likely culprit)
This is a Windows 11 feature that often conflicts with kernel-level Anti-Cheats like EAAC.

Path: Go to Windows Security ＞ Device security ＞ Core isolation details.
Action: Toggle Memory integrity to OFF.
Note: Windows 11 will require a Restart for this to take effect.
Reason: This feature uses hardware virtualization to protect memory, but it often clashes with how EAAC scans for cheats, leading to a system-wide hang or low FPS.

2. Disable "Exploit Protection" for BF6
Windows 11 has aggressive built-in defenses that can overreact to the Battlefield engine.

Path: Go to Windows Security ＞ App & browser control ＞ Exploit protection settings (at the bottom).

Action: 1. Click the Program settings tab.
2. Click + Add program to customize ＞ Choose exact file path.
3. Navigate to the folder where BF6 is installed and select bf6.exe.
4. Scroll through the list and find these 3 items. For each, check "Override system settings" and set them to OFF:
* Control Flow Guard (CFG)
* Data Execution Prevention (DEP)
* Mandatory ASLR (Force randomization for images)

3. Run as Administrator & Disable Fullscreen Optimizations
Right-click bf6.exe ＞ Properties ＞ Compatibility tab.

Check "Run this program as an administrator".
Check "Disable fullscreen optimizations".

Reason: This ensures the game has enough permission to operate alongside Windows services and prevents the Windows display manager from interfering with the game's high-performance mode.

Note: Please restart your PC after applying these settings and see if you can pass the 20-40 minute mark. If this works, it proves the issue is an "Inter-operation" conflict between the OS and the BF6 game.

Good luck!
