Unexpected Error in 3D Capture Photoset Alignment

Hi!

I've just got started on Adobe Sampler and I'm trying to convert a set of images from a product photoshoot into a 3D object. 

Importing the photoset goes fine, but it comes up with "an unexpected error occured" in the alignment process. 

I made the images transparent PNGs in the hopes that it would be super easy for the AI to find the object but even with bight green background JPEG, it threw up the same error.

Any advice?

My PC specs are attached, as well as a error log and a screenshot of the error!
