Hi, are you using the desktop OneNote app or the Windows 10 app version?
Open OneNote in safe mode to isolate add-ins, press Windows key + R, type onenote /safe, then press Enter. If it works, go to File, Options, Add-ins, then disable all add-ins and restart normally. If the issue remains, repair the app by going to Settings, Apps, Installed apps, select OneNote or Office, choose Modify, then run Quick Repair followed by Online Repair if needed. This resets app components and restores normal navigation and ribbon behavior.
