ERROR_SXS_SYSTEM_DEFAULT_ACTIVATION_CONTEXT_EMPTY

ERROR_SXS_SYSTEM_DEFAULT_ACTIVATION_CONTEXT_EMPTY — Windows could not generate the activation context for the system default assembly.

The system default Side-by-Side assembly context could not be created. This is broader than a single application manifest error and may indicate damage to the Windows component store or interrupted servicing.

Do not attempt to rebuild the system default manifest manually. Check the component store and repair it through Windows servicing tools.

What to check

Review SideBySide and CBS log entries around the first occurrence.
Run a DISM component-store health check, then repair if it reports corruption.
Run SFC after the DISM repair to validate protected system files.

DISM /Online /Cleanup-Image /ScanHealth

DISM /Online /Cleanup-Image /RestoreHealth

sfc /scannow
