Hi, I'm John! I will help you with this.
Have you already clicked Repair Now? If yes, what happened afterward? Did the repair complete successfully, or did you receive an error message?
If the issue continues, click Reset in the same window. Make sure your notebooks are fully synced to OneDrive before doing a reset.
Let me know the version of OneNote you are using and the exact repair message, and I can provide more specific steps.
