Unable to Import USDZ Model

I have a USDZ file that is only 33.8MB that images fine on my Mac in Preview and QuickLook, but when I try and import it into Stager, after it thinks for a few seconds, and the progress bar is about half way through, it pops up a dialog saying it can’t import it and report it here;

Unfortunately I can’t share the data, but if there’s something I can check locally happy to do it.
