Hello, and welcome to Sysnative!
I'm really sorry for the delay in responding. Thanks for alerting us to it.
Unfortunately, error code 0x80073712 is a really bad sign. Most error codes mean that a certain component is corrupt. We can usually fix them. This error code usually means that every component is corrupt (give or take, it's a bit of an oversimplification but I think you get the idea), and unfortunately that is not fixable in the conventional ways (instead we must look into trying to get a Repair Install to work).
Can you please navigate to C:\Windows\System32\config
and tell me the file size of the COMPONENTS file (no file extension).
Thank you, and I'm really sorry to be the bearer of this news.
