Unable enter game due to EA Anticheat update problem

Since the latest anticheat update (2025-12-12), I can't enter the game, for both BF1 and BF5. It first pops out the dialog says "need latest anticheat (115)".

So I download the anticheat file, throught this link https://cdn.eaanticheat.ac.ea.com/EAAntiCheat.Installer.exe, and update it.  After update, those 3 following files "EAAntiCheat.GameService.dll, EAAntiCheat.GameService.exe, preloader_s.dll" became to (2025-7-11) version. 

Then, i repair the game, the modified time of those 3 files under the game directory, "EAAntiCheat.GameServiceLauncher.dll, EAAntiCheat.GameServiceLauncher.exe and preloader_l.dll" will became to the date of repair time. (that make sense i thought). 

But when i start the game, the anticheat or some other ea program, will reverse my latest "EAAntiCheat.GameServiceLauncher.dll, EAAntiCheat.GameServiceLauncher.exe and preloader_l.dll" under the game directory back to the 2025-7-11 version, and change name of the latest "EAAntiCheat.GameServiceLauncher.dll, EAAntiCheat.GameServiceLauncher.exe and preloader_l.dll" to "EAAntiCheat.GameServiceLauncher.dll_b, EAAntiCheat.GameServiceLauncher.exe_b and preloader_l.dll_b"

Then the dialog says "need latest anticheat (115)" pops again and again. try several time. 

Please advice and say something to your test team, apparently someone is not do their jobs.
