Hi Andy,
Since you're on the latest version of OneDrive, here are some few things we suggest you try:
- Ensure that OneDrive process is running. Open Activity Monitor under the
Applications > Utilities or use Spotlight to search for it. Select the
CPU tab, then look under the Process Column for OneDrive. If OneDrive is not running, use
Finder or Spotlight to start it.
- Restart your OneDrive by clicking the OneDrive icon in the menu bar and selecting
Quit OneDrive. Then start it by searching OneDrive using Spotlight.
If the above two doesn't work, you can also try resetting your OneDrive sync client and verify if the issue will remain.
- Exit OneDrive.
- Find OneDrive in your Applications folder
- Right-click and select “Show packaged contents”
- Navigate into the Contents/Resources folder
- Double tap on ResetOneDriveStandaloneApp.command
- Start OneDrive and finish the setup process.
You can refer to the article below for your reference.

We also would like to confirm the following:
- Did you make any changes on your Mac prior to the problem?
- Does it happen to any files? If not, what specific file types are affected?
- Have you tried syncing the files to a different folder or library?
