Sent this to BattlEye. Received an automated reply recommending I follow their FAQ to fix the problem. No human seems interested in responding. Note the email is lengthy, feel free to scroll past the code snippet. =start of email= to BattlEye I have completed further research regarding this issue. It appears your driver has been deemed vulnerable by Microsoft, and is on a block list. See: https://learn.microsoft.com/en-us/windows/security/threat-protection/windows-defender-application-control/microsoft-recommended-driver-block-rules Text from this page that may prove helpful: Drivers can be submitted to Microsoft for security analysis at the Microsoft Security Intelligence Driver Submission page. For more information about driver submission, see Improve kernel security with the new Microsoft Vulnerable and Malicious Driver Reporting Center. To report an issue or request a change to the vulnerable driver blocklist, including updating a block rule once a driver vulnerability has been patched, visit the Microsoft Security Intelligence portal or submit feedback on this article.

Thank you for any assistance in resolving the issue. =end of email= With four companies (Steam, Bungie, Battleye, Microsoft) all intermingled with this problem, I am uncertain about it ever being resolved. Just getting a human pair of eyes on this seems impossible. Sad state of affairs.
