Hi, @lalajee

Thank you for posting in Microsoft Q&A forum.

2023-05-19 15:42:43 Start: GetConfigValue with filename=UpdateServices-Services.xml item=ContentLocal

Please try renaming file name UpdateServices-Services.xml to updateservices-services.xml.old. Then run post-install again.

(UpdateServices-Services.xml is under c:\windows\system32\servermanager\componentconfiguration)

If issue persists, please try to remove wsus role , wid, delete database file, reinstall wsus again.
