Hello,
Welcome to Microsoft Q&A!
Registration of the app failed. [0x80073CFD] Windows cannot deploy to path AppX of file system type exFAT.
I have to say, you can't install the appx in exFAT file system, derive from the document. A packaged application always runs as an interactive user, and any drive that you install your packaged application on to must be formatted to NTFS format. So the only support file system is NTFS format for UWP app.
Thank you.
