Can I insert Prezi presentations using SlideDynamic has changed the structure of the presentations that are played from your online account and as a result, they are no longer compatible with SlideDynamic. Also, newer versions of the desktop software are also no longer compatible with SlideDynamic and there is no way to insert them into a PowerPoint presentation. 

The only way to insert a Prezi presentation into PowerPoint is to use a previous version of Prezi Desktop (version 4.2) and use the Export Portable Prezi from that along with the SlideDynamic feature "Insert Offline Prezi".
