It sounds like you've already tried the common troubleshooting steps. If OneNote started crashing only recently, check whether a recent Windows or Microsoft 365 update coincided with the issue. Try opening OneNote in Safe Mode (Win + R → onenote.exe /safe) to rule out add-ins or startup issues. Also, ensure your graphics driver is up to date, as hardware acceleration or outdated drivers can sometimes cause freezing. If the issue persists, try using OneNote on the web to access your notes temporarily and report the problem through the Feedback Hub or contact Microsoft Support, as this may be a recent bug affecting the desktop app.
