Keyboard Shortcuts Not Working
You can either resolve by right-clicking somewhere in the application window, whereafter the shortcut keys start working again.
Also - I found that changing the settings in OneNote (Preferences > Edit and View > Default Paste Option (choose one of the options), fixed it for me for both OneNote and PowerPoint that I don't have to right-click first anymore.
