Server 2019 Cumulative Updates Failing

Have been having an issue with two servers that were installed under the same windows ISO image. Both have failed to apply cumulative updates since December. They download and install but upon reboot fail to fully apply with the error codes 0x80240034 and 0xca00a000. At this point have already tried resetting windows update, running DISM, SFC, CHKDISK, and using the windows update troubleshooter but the problem persists. Here is the output of Get-Hotfix should it provide any guidance.

    Remove any patches that the system has installed. This should get it back to RTM or at the very least, 1-2 months before (October/November patch level).
    Restart the server 2 times, to ensure a CLEAN boot.
    Download the latest CU from the catalog
    Open an elevated CMD
    run the msu file of the latest CU by executing it from the elevated CMD.

    If that doesn't work - time to install a new one and migrate over.

    Some things to try
    https://learn.microsoft.com/en-us/windows/deployment/update/windows-update-resources#reset-windows-update-components-manually
    sfc /scannow
    dism /online /cleanup-image /restorehealth
    and also a repair install by running setup.exe from the root of install media

    Seems the instance is beyond repair. Time may be better spent standing up a new one, patch fully, migrate roles over to it and move on.
