Hello, and welcome to Sysnative :)
• Please download the System Update Readiness Tool from Microsoft ->
here<-. Save the tool to a convenient location as it may be necessary to run it again.
• After the download has completed, double-click the file and wait while it initializes.
• Click Yes to begin installation.
Once it has finished (please be patient, it may take 45mins to an hour to complete), please copy to Desktop, zip up, and upload
C:\Windows\Logs\CBS\CheckSUR.persist.log.
This is quite unlikely to fix your issue (that will be next post), but I need to assess the state of the system before making the fix. It is possible that various files that should have been updated over the reboot have not been fully updated, and could be left in an inconsistent state if we just reset the reboot flags.
Thank you!
Richard
