The original WinSCP directory listing in the right-hand pane is replaced by a single entry for ".." (meaning go back up to the parent directory). So it looks like a directory listing, but no file or directory names appear after the ".." entry. A screenshot showing the error message and the resulting directory listing for the file is attached.

Please explain in more details, what happens when "the file being treated as a directory name".

Root SSH access works fine in WinSCP 6.3.3.

However, specifying user spring, with correct user password, allows viewing directories and files on the remote Alma Linux/Webuzo server.

Files can be downloaded successfully.

However, an attempt to double-click a file to open it locally in Notepad fails, with the file being treated as a directory name. This failure does not happen for a site for user root.

User spring has rw access to the file.

The log is attached.
