Did you follow the steps in "Restore deleted files or folders in OneDrive"?
As a tip said in it, "As an Microsoft 365 subscriber, you can even restore your entire OneDrive if something goes wrong."
So if you are an Microsoft 365 subscriber, maybe you could try to restore OneDrive to see if you could see the deleted files.
Generally, as I know, on the PC side, local files and cloud files are highly unified.
Take Word documents, Excel workbooks and PowerPoint presentations for example, if you delete them on the local PC, they will also be deleted in the cloud.
On the other hand, if you delete these files in the cloud, the files on the local PC will also be deleted.
Hope the information could be helpful to you.
