This is what I have online after creating 08-wim with W10UI and then installing it. For 2020-09, I used WUMT to update online (14393-0onl_LTSB+09_a-r.txt) Then ran a resetbase and manually removed the previous SSU what I thought was superseded (14393-0onl_LTSB+09_rmu.txt) and so far the system is running fine. Will see next month if having removed 4565912 causes any issues.
The problem is with pre-updated ISO install, not online running OS. What exact updates were in the wim before you installed it?
About to try. EDIT : Same here : 0X800F0984 This is a heavily modified system though. Going to retry later today doing an in-place upgrade from 508 to 538.
