I've noticed similar issues with OneNote on Windows 11, so you're not alone. Syncing problems and crashes can be frustrating, but here are a few things that might help:
Update OneNote and Windows: Ensure both OneNote and your Windows 11 OS are fully updated. Microsoft often releases patches for known issues.
Repair OneNote: You can try repairing the app by going to Settings > Apps > Installed apps, finding OneNote, and choosing "Modify" or "Advanced options," then selecting "Repair."
Re-sync your notebooks: Sometimes manually syncing can help. Go to the Notebooks section and choose "Sync this notebook" if you're using the desktop version.
Check for Conflicting Software: Some third-party antivirus or security software can interfere with OneNote's functionality. Consider temporarily disabling them to see if performance improves.
Optimize your notebooks: Large notebooks can cause crashes, so breaking them into smaller sections or archiving old files might improve stability.
If these don't resolve your issues, checking Microsoft support forums or user-reported issues online might give more insights, as this is a known concern for many with the upgrade. Have you found any of these tips helpful, or is there another aspect of the problem you'd like to explore?
