Windows Updates Failing

Hello,

I have a couple updates failing on some Windows Server 2019 hosts.

KB5009718 Error 0x800f0922
KB5009557 Error 0x80071ab1

I've tried standard things like:
Renaming the SoftwareDistrubtion and catroot2 folders
I ran sfc /scannow and dism /online /cleanup-image /scanhealth which didn't return any errors.
I downloaded the MSU files directly from Microsoft and attempted to install them. That failed.
I also extracted the MSU files and tried installing the cab files via DISM which also failed.

I've attached the cbs.log file from one of the hosts. Does anyone have any other suggestions to try?

Thanks

    Sounds like dotnet may be broken. A couple of things to try are a recent dotnet repair tool or also and in-place upgrade (repair) by running setup.exe from the root of the installation media. Also check the known issues here as you may want to hold off on kb5009557
