Which version of OneNote do you have? Click the 3 dots at right, Settings, About.
I have Version 16001.11629.20028.0 which probably is part of Office 2016 [app Version 16] but apparently came as part of a Win10 update.
I actually have Office 2000 [app Version 9] installed which did not include OneNote.
It could be version conflict, sometimes happens with updates.
