KB5032196 reports the Bitlocker Device Encryption reporting issue. The issue was first reported after the deployment of the October 2023 cumulative update KB5031361. It is essential to note that the issue is a reporting issue only and actual device encryption is not impacted.

Using the FixedDrivesEncryptionType or SystemDrivesEncryptionType policy settings in the BitLocker configuration service provider (CSP) node in mobile device management (MDM) apps might incorrectly show a 65000 error in the “Require Device Encryption” setting for some devices in your environment. Affected environments are those with the “Enforce drive encryption type on operating system drives” or “Enforce drive encryption on fixed drives” policies set to enabled and selecting either “full encryption” or “used space only”. Microsoft Intune is affected by this issue but third-party MDMs might also be affected.

To mitigate this issue in Microsoft Intune, you can set the “Enforce drive encryption type on operating system drives” or “Enforce drive encryption on fixed drives” policies to not configured.
