Hi,
Our product team has investigated the issue on their end. Actually, thee root cause of this issue is that shared PPT contains non-valid oleObjects and that you can ensure by re-saving presentation to PPTX format using Powerpoint 2010 or just opening it using PowerPoint 2016. We have created separate issue to add ability to load PPT with corrupted OLE object, but this could take some time. For the time being, you may please try saving presentation using PowerPoint first and then try again.
Best Regards,
