How do I open a document that L.O. says doesn't exist

I created a document in L.O. and placed it in a file to work on later. Now I cannot open it although I can see it. I get a dialog saying “The document cannot be opened because it doesn’t exist.” I can see that it exists. How do I open it.

EDIT_ebot Taken from answer of @Shamanomaha, answer deleted:

I conclude the document exists because I can see it it in the “Recents” folder in L.O.

I can see that it exists.

From which observation do you conclude that it exists? From the thumbnail in right pane of LibreOffice?

I cannot respond to your question because it is a “no-reply” message. When I try and open my comment I see a notice that my question is deleted. ???

To answer, please edit your initial question or write a comment. **Do not post answers**, if it is not a solution to your question. Thank you.

I conclude the document exists because I can see it it in the “Recents” folder in L.O.

And this conclusion is based on a complete misunderstanding of the nature of “Recent documents” list. An entry in recent documents list is just a reference to the file (just like a link on a webpage to some other page) where it was stored, when it has been opened/and saved for the last time. If you or some process delete a file after its last opening from your system, then the entry in recent document won’t get deleted as well. And the reference to that file will point to nowhere (since the file is no longer there). So if you need to open your file, use menu File -> Open and search the place where you stored (saved) the file to.

Did you move your file somewhere? For example in Explorer via CutPaste
