Hello jmark03.
This has been addressed in the BattlEye FAQ: https://www.battleye.com/support/faq/

Recently Microsoft has started to ask Windows 11 users to enable this security feature and if they do so it will cause the BE driver to be unable to load. Due to the complexities involved in security software unfortunately many kernel-level anti-cheats, including BE, are not compatible with this feature yet. While we are working on finding a solution and are also in contact with Microsoft regarding this issue, unfortunately there is no easy or immediate fix for it.

Therefore, for the time being, users will have to revert enabling this security feature using one of the following ways. Please note that by doing so you will not lower the security of your device or expose it to greater risks compared to previously, as this is a new security feature that wasn’t enabled on devices before.

Click the “Disable” button in the Windows popup and reboot your system.
Open the Start menu and enter “Core isolation” in the search bar to open the related Windows Defender settings. In the “Windows Security” window switch the option called “Kernel-mode Hardware-enforced Stack Protection” to “Off”, then reboot your system.
Afterwards you should be able to play BE-protected games again.
