It would seem that, that is saying that the file "ProduKey.cfg is stored in your profile folder which contains your OneDrive\Desktop folder
Not sure why you've included your Desktop folder in your OneDrive folder.
I've checked all of mine and I have no Desktop folder in any of my OneDrive folders on all my machines.
Assuming you have a good backup of everything (disk image), you might try launching OneDrive "settings" (just right click the Icon in the notification area and select it from the context menu)
AND "Unlink" this PC and start over excluding "Desktop" it's not generally even a choice, so.....
I'm not sure how you managed to tie your desktop folder into OneDrive unless you perhaps moved it with the location tab.
You might want to investigate that by checking the properties of your desktop folder in C:\Users\YourUserName\Desktop, under the location tab
