Unable to access photos through app or download

I have the Dropbox app installed (Windows 10) and am getting the message that my Dropbox is full. I have no files in the local Dropbox folder.

When I sign into Dropbox on the web, the only place I see items is under "Photos." These photos are NOT in my local Dropbox folder.

When I attempt to download a photo, I get the error message "There was an error downloading your file."

I saw the suggestion to create a share link and use that to download the pictures. When I attempt to do this, I click "Share Link" and then "Copy link." I get an error message "Something went wrong..." at the bottom of the screen.

This happens:
- On two different computers.
- In and out of Incognito mode.
- In both Google Chrome and Firefox (no error messages in Firefox, but nothing happens).

I cannot copy the file. The only action I can take is to delete the file. The file is deleted, but does not appear in my Deleted files.

In the Dropbox app on both computers, the Activity tab shows the pictures I view on the web so there is some connection. But the photos are not downloaded to my computer.

Please advise how I can get these photos out of Dropbox to free up space.

Thank you.
