OneDrive DELETED user libraries and files

I'm sorry to hear about the issues you've been experiencing with OneDrive and your user libraries. Losing important files can be frustrating, but let's try to troubleshoot the problem and see if we can recover your data.
Firstly, it's worth noting that reinstalling Windows 11 might have caused the local user libraries to become unlinked from OneDrive. When you set up OneDrive again, it could have synced with an empty cloud storage, resulting in the disappearance of your files. However, it's puzzling that your local libraries also disappeared.
Here are a few steps you can try to recover your user libraries:
1. Check the "OneDrive" folder: Open the OneDrive folder on your computer and verify if your files are located there. By default, the "Documents," "Photos," and "Downloads" folders within your user directory should sync with the OneDrive cloud storage.
2. Use the "Restore previous versions" feature: Right-click on the parent folder of the missing libraries (e.g., the "Users" folder), and select "Restore previous versions." This feature allows you to recover files or folders that may have been deleted or modified in the past.
3. Use a data recovery software: If the above methods are not successful, you could try using a data recovery software. These tools scan your hard drive for deleted files and might be able to recover them. However, keep in mind that the success of data recovery depends on various factors, including how long ago the files were deleted and whether any new data has overwritten them.
If none of these options work, your best bet may be to contact Microsoft Support or a professional data recovery service for further assistance. They may have additional tools or methods to help recover your lost files.
In the future, I would recommend regularly backing up your important files to an external hard drive or a separate cloud storage service to ensure their safety.
