  4. Here, toggle the switch to Off for Kernel-Mode Hardware-enforced Stack Protection.
  5. To reactivate it once your session is complete, just switch it back to the “On” position.
  6. Make sure to restart your PC after enabling/disabling Kernel Stack protection.

Disable Your Antivirus Software

Surprisingly enough, your antivirus software can be one of the bigger reasons why a game might be crashing or experiencing errors like EAC error 30005. This happens when an antivirus software mistakes such an application for a potential virus. This phenomenon is not very uncommon and could be the reason behind the Armored Core 6 easy anti-cheat error 30005.

Disabling Windows Defender

To check if this is indeed the case, first turn off your antivirus software and launch Armored Core 6 to see if the error gets fixed. Here’s how to disable the Windows Defender:

  1. Press the Windows icon on your keyboard and open the start menu.
  2. Click the gear icon to enter Windows system settings.

Whitelisting Game Directory

In case you are running any other 3rd-party antivirus software, disable it as well. Now, relaunch Armored Core 6 once more to check if the issue has been resolved. If the error persists, skip this method and move to the next solution. However, if the error has been fixed, you must now whitelist Armored Core 6 and Steam in your antivirus software.

This is an extremely important step, as it’s never recommended to keep your antivirus software disabled forever. Doing so can be highly risky because foreign threats will easily be able to penetrate your system and steal sensitive data.

Here’s how to whitelist applications in the Windows Firewall Defender:

  1. Get to Windows Security again. (See the first three previous steps.)
  2. Click on Virus & Threat Protection. This will open a completely new security window.
