Open the file in PowerPoint and directly save it again to ppt-format. Now do opening and saving to pptx in LO with that file. I see no error. So there is something special in the ppt file which is removed by modern PowerPoint.
The opened file has in "Segments" in "Path" in "CustomShapeGeometry" a lot of segments with "Count" -21504. That is surely wrong, because "Count" has to be non negative. Such does not exist when the file is opened, which was resaved by PowerPoint. So I think, that there is something faulty in the file, which is repaired by PowerPoint. And the error is not in the export part, but we would need to repair the file on opening, as PowerPoint does it.
