Apparently this is cause of too high app version number:

I changed the app version number to 1.0.1.77 and the Add-PnPApp is working as usual. I think the actual bug is that the error message is not getting through.

@djsladi Running into a similar issue. Where did you change the app version number?

@djsladi ran into this same issue because i was appending the build number to the version number. removing the build number worked for me.
