    Howdy Denver. I’ve experienced similar issues before. I guess a recently installed update might have caused this issue (But I say this based on previous experience alone).
    I recommend opening a support ticket with Microsoft. Run the Recovery Assistant for Office 365 (SaRA) tool and send Microsoft the results.

DCOM hardening issue.

This application fails to authenticate with WMI on the SCCM server because Microsoft has not yet hardened DCOM on their Windows Preinstallation Environment. We are working on a different approach, but it will only be released during the first quarter of 2024. But until that time, the only workaround will be to uninstall the update corresponding to KB5004442.
