BF6 won’t launch (black window, no error)

Ok quick update on the additional steps I have taken:

System:

• Windows 11 Pro (25H2, Build 26200.6725 – KB50665789)
• UEFI BIOS: Gigabyte Z390 AORUS ELITE-CF, Firmware F12c (June 2025, Secure Boot enabled)
• CPU/GPU: Intel i9 / NVIDIA RTX (latest driver 581.42, clean DDU install)
• Drives: All GPT + NTFS (converted from mixed GPT/MBR layout)
• EA App on C:, Battlefield 6 installed on G:\ (GPT SSD)

Steps Already Taken

1. Clean Windows 11 Reinstallation: Fully wiped and reinstalled using official Media Creation Tool. Installed latest chipset, LAN, and MEI drivers from Gigabyte support. Applied all Windows Updates including September 2025 Cumulative Preview (KB50665789).
2. Firmware & BIOS Updates: Updated motherboard BIOS from F9 (2019) to F12c (June 2025). Enabled Secure Boot and verified “Windows UEFI Mode.”
3. Storage Format Consistency: Converted all internal drives to GPT + NTFS using EaseUS Partition Master. Confirmed no legacy (MBR) partitions remain.
4. GPU Stack Refresh: Used DDU in Safe Mode to remove all NVIDIA drivers. Performed a clean install of driver 581.42 and NVIDIA App (works correctly now).
5. EA AntiCheat Diagnostics: Attempted manual service registration via command line, but sc query "EA AntiCheat Service" always returns Error 1060: The specified service does not exist as an installed service. Tried uninstalling and reinstalling using both EA App and manual commands – no service is created.
6. System Integrity Checks: Ran sfc /scannow and DISM /online /cleanup-image /restorehealth – no violations. Verified WinDefend service running and Secure Boot key configuration valid.
7. Peripheral & Driver Conflicts: Removed legacy Razer software and checked Event Viewer for related faults (none remain).
8. Hardware Validation: Confirmed all disks GPT, all firmware Secure Boot–compliant, no virtualisation errors, VBS enabled.

Hypothesis:

EA AntiCheat fails to register its kernel service when multiple drives or residual Storage Spaces exist, possibly due to conflicts in Windows’ virtual disk enumeration.

Given all UEFI, GPT, and driver requirements are met, the issue likely lies within the EAAntiCheat installer logic.

Next Planned Test:

Delete any Storage Spaces / Storage Pools under

Settings → System → Storage → Advanced storage settings → Storage Spaces,

then retry Battlefield 6 launch (per reports that orphaned pools can block EA AntiCheat initialisation).

Request:

If anyone has managed to resolve this without disabling Secure Boot or reinstalling Windows again, please share how the EA AntiCheat service registered successfully.

All logs and event traces can be provided upon request.
