EA BuG WITH STARTING EA ANTI CHEAT

Subject: Apex Legends won't launch - EA Javelin Anticheat service fails to start (Event 7023, Error 87)

Hello,

Since the new EA Javelin anticheat was added to Apex Legends, the game will not start. It shows "Starting EA Anticheat" and then the window simply closes.

SYSTEM

- Windows 11 Pro, version 26H2, OS Build 26300.9550

- CPU: AMD Ryzen 7 7700X, RAM: 32 GB, motherboard: ASRock B650M-H/M.2+

- BIOS: UEFI, Secure Boot: On (BIOS version 2.10, 3/20/2024)

- Apex Legends installed through Steam

PROBLEM DETAILS

- EAAntiCheatService exists in services.msc (startup type: Manual) and the files are present in C:\Program Files\EA\AC (EAAntiCheat.GameService.exe, EAAntiCheat.GameService.dll, preloader_s.dll).

- Starting the service manually gives: "Windows could not start the EAAntiCheatService service on Local Computer. Error 87: The parameter is incorrect."

- Event Viewer (System log) shows Service Control Manager Event ID 7023: "The EAAntiCheatService service terminated with the following error: %%4294938639".

WHAT I HAVE ALREADY TRIED

- Uninstalled and reinstalled Apex Legends several times.

- Ran EAAntiCheat.Installer.exe as administrator, used Repair and selected the Apex Legends folder (...\steamapps\common\Apex Legends). The installer log ends with "ServiceInstall success", "CertificateInstall success" and "Install success".

- Steam launch options are empty.

- Memory integrity (Core isolation) is turned off.

- Microsoft Visual C++ Redistributable v14 (x64) 14.51 is already installed (newer than the current download).

- FACEIT anticheat service is installed but stopped.

I suspect this may be a compatibility problem between EA Javelin and Windows 11 26H2 (build 26300). Could you please confirm whether this Windows version is supported, and advise how to fix it? I have attached my DxDiag report.

Thank you.
