Microsoft has implemented a new upgrade block for Windows 11 24H2 affecting systems with Dirac audio enhancement software. The compatibility issue, linked to the cridspapo.dll component, causes audio devices to malfunction after the update.

Key Issues:
– Applications fail to detect audio devices
– Integrated speakers become non-functional
– Bluetooth speakers and headsets stop working
– Both first-party and third-party apps affected

Microsoft’s Response:
– Implemented safeguard hold (ID: 54283088)
– Preventing automatic updates on affected devices
– Working with Dirac for driver solution
– Will distribute fix through Windows Update

User Guidelines:
– Avoid manual updates via Windows 11 Installation Assistant
– Don’t use Media Creation Tool until resolution
– Check for safeguard holds through Settings > Windows Update
– Watch for “Upgrade to Windows 11 is on its way” message

This block follows recent Windows 11 24H2 compatibility issues, including Auto HDR-related game freezes. The upgrade restriction will remain until Dirac releases updated audio drivers and Microsoft verifies the fix.

Users can verify their system’s status through Windows Update settings or consult the KB5006965 support document for detailed information.
