Hello, thank you for reaching out to Microsoft Q&A.
You may receive this error if the file has been corrupted or deleted from your system. If the files were saved in OneDrive and you are experiencing a sync error, this type of issue may occur.
'Right-click the OneDrive icon on the taskbar and check if there are any sync errors. Share the error message if you see one'
To restore your lost files, please let us know where they were saved. For example, were they stored in OneDrive or in a local desktop folder?
- If you saved the files online or synced your Documents folder with OneDrive, you can try accessing them through OneDrive online. To do this, go to OneDrive, select the My files section, and then open the Documents folder.
