Windows Driver Error 1275 Displayed When Running Epic Games Battleye Anti-Cheat. [Fortnite]

Windows driver error 1275 is displayed when trying to run a game using Epic Games Battleye Anti-Cheat Protection Software. [Necessary to run the game Fortnite.]



Epic is researching the issue related to the Windows Core Isolation [Hardware-Enforced Stack Protection] security protocol.

Enabling this option in Windows settings will not allow BEDaisy.sys [a core Battleye component] to run.

Currently the only [temporary] fix is to disable Core Islotation:

    - Click the "Disable" button in the Windows pop-up dialog window if displayed and reboot the system.

    - Click on the Windows "Start Menu" icon and type "core isolation" into the search box, click the "system setting" icon, this will open the related Windows Defender Security setting window.

    - Click to disable the Kernel-Mode Hardware-Enforced Stack Protection option.

- Reboot the system and the issue should resolved until a patch is released where you can re-enable this option.

Epic Games notes that disabling this service the does not lower the security of the system, or expose it to greater risks as it was a feature that was previously disabled by default.


We hope this issue will be permanently resolved in the near future.
