Subject: Easy Anti-Cheat "Untrusted System File" Error (amdihk64.dll) on RX 590

Hello,

I am consistently receiving an "Untrusted system file (C:\Windows\System32\amdihk64.dll)" error from Easy Anti-Cheat while playing Apex Legends. This happens either immediately upon launch or within 5 minutes of gameplay.

I have already tried the following steps to resolve the issue, but none of them worked:

Performed a clean driver uninstallation using DDU in Safe Mode.

Installed the latest AMD WHQL (Recommended) drivers (Adrenalin 26.1.1).

Repaired/Verified game files via EA App/Steam multiple times.

Manually took ownership of the DLL file and ensured it is up to date.

Checked for Windows Updates and ensured the system is current.

Despite having a legitimate and digitally signed AMD driver, EAC continues to flag this specific DLL as untrusted. This issue started occurring after the latest 11GB game update.

Could you please investigate if this is a known compatibility issue between the latest EAC version and AMD RX 500 series drivers?

System Specs:

GPU: AMD Radeon RX 590

OS: Windows 10

Driver Version: Adrenalin 26.1.1 WHQL

I've been getting the amdihk64.dll error for days and I can't even enter the game. I tried DDU, WHQL drivers and verifying files but nothing works. This started after the 11GB update. Please fix this EAC issue for RX 500 series users. It is very frustrating.

If you are coming here for thi sissue:
1. Unininstall the AMD Adrenalin software this will uninstall you driver. reboot
2. If you have the previous driver installer, reinstall (If not download the previous version)
3. DO NOT install the other Adrenalin software and DO NOT upgrade your driver. For gods sake DO NOT turn on any automatic updates for video drivers!

Why this happens:
Drivers get updated and pushed out before the game devs has enough time to identify all breaking changes. Wait until trhe game devs have time to make their updates. Honestly unless there is a critical bug fix or a vulnerability, if it works DON'T FIX IT!
