How do I synch the new release (7.04) of LibreOffice with old files created with earlier releases?

I just downloaded the new release (7,04) of LibreOffice without issues. However, when I now try and access my old files created with previous releases, I get an error message saying that the files do not exist. How can I resolve this issue?

Did you move or delete any of those files? LO remembers when you last opened or saved a file, it doesn’t keep track of what you do with those files in the file manager of your operating system.

Open LibreOffice Writer, click File > Open. In the dialog that opens, navigate to where you stored your documents, select the document that you want to open and click the Open button. The file will open
