Hi Michael,
Apparently Katherine saw your keywords “This workbook is either deleted or not currently accessible” and slapped in a stock reply she uses whenever she sees those particular keywords. That's typical behavior for an AI bot. I'm not sure that Katherine's reply has much relevance to your situation.
You said, "The file is still there." But that raises some questions. It sounds to me that you are telling us that the file is still listed under recent files and you have concluded, based on the error message, that the file was deleted. If my interpretation of what you said is correct, you may be jumping to conclusions.
The recently used file list is a collection of shortcuts. The shortcut breaks If any part of the path changes (an enclosing folder was renamed, or perhaps there's a new name for the startup drive, or if saved to a cloud or server the symbolic link changed, or there was a corrupt file system, or there was one or more special characters in the file name or enclosing folders). The message you received doesn't necessarily mean your file was deleted, but if it was deleted, that would certainly trigger the notification.
We know this: your workbook was saved somewhere at least once. The question is, "Where was the file saved?" You can find that out easily. Use the Menu Bar and choose File > Open Recent > More. The path to the most recently saved version is displayed under the file name. Knowing the type of device the file was saved to is essential information before anyone can tell you how to recover your file. Was it saved to your Mac? OneDrive? SharePoint? iCloud? A flash drive? A network drive? Each device type has its own recovery steps to take. If you reply with the device type, we can explain how to recover your file on that kind of file system.
