So did the sfc /scannow report it was unable to repair some files ?
It would seem that SFCFix.exe doesn't look upon those duplicate ownership as corruption/errors.
In Event Viewer ensure Event Viewer (Local) is highlighted in the left pane - if it isn't then just click on it.
When it has read the data, click on the name Error then on View All Instances of This Event in the lower right pane then look for a date and time stamped event for when the program failed to run.
Clicking on any will produce a bit more info in the pane below.
You can copy & paste any after clicking on them by clicking on Copy/Copy details as text in the lower right pane then right click in the reply box and select Paste.
(I'll probably have to use Google Translate to read them
)
I've had a Google for that duplicate ownership which others have also had in Win 10 and other versions of Windows with so far, no solution.
Could you turn your UAC down or off before trying Tweaking again to see if it's that.
I'm going to ask my Support to have a look at your CBS log to see if any of the duplicate ownerships could be the cause of the program not running.
I won't be hiding any eggs anywhere but have given Easter eggs to my grand kids - well I still call them kids even though one has turned 18
Happy Easter to you as well - I've been meaning to Google to see why we have eggs at Easter
