Hello Franklin,
A reset keeps the existing system you have. Exactly what build are you on? Appears you must be on a Dev build dated back in July. I suspect you have already deleted the self-host key and turned off diagnostic data. This could be why your updates are always failing as you are still on a dev build of 26120.xxxx
Suggest deleting the entire WindowsSelfHost Key once more:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost
Please look in Control Panel or Settings for the enablement package kb5037898 and uninstall.
Reboot your system and please report back using winver on what build you are on.
Regards,
