Only time I have seen behavior like this it was a disk permissions issue on a MAC using an external Drive, and I think the MACTF file is a MAC OS thing, not an excel thing.
If we made a new excel, saved it locally and moved it to the external drive it was fine. You could read it, open and edit, but trying to save it would cause the error again. It was because Excel didn't have full access to the secondary drive so the mac would kill it on save attempt, and throw errors.
We had to add the Excel application (and the Drive's client software) to Full Disk Access in System Preferences - Security & Privacy.
