Can't save file if it already exists

Student Edition 2025 SP5.0

When overwriting a file  (simple save) SW does not update the file on the hard drive.

When "save as" with the same name I get a warning (I acknowledge) but file is not updated.

Save as with a new name works.

Notepad ++ works in the directory, so its not a windows permission issue.
