Deleting Truncated (shortened/damaged) Files: Studio 4.5

An error message shows ‘Error reading - truncated files’ - when I save my project but there is no file name. The window that appears when you save, showing a rapid sequence of numbered files being saved, stops on drawing numbers, are these the 4 truncated files? they don’t appear in the exposure sheet, library or timeline.

… file seems to be righting itself.
