Error formatting NTFS when trying to restore image with a package

I’m running into issues restoring a Windows 10 1809 bootcamp image from a 2018 Mac mini to a 2018 MBP.
I’ve created the image using the latest version of winclone on the Mac mini, then created a package and copied it over to the MBP. When I run the package it fails after about a minute. It looks like the issue is The volume could not be formatted as NTFS. Check the drive and try again.

I don’t really know why. The MBP is running 10.14.4 and has an APFS filesystem. I have tried the package several times.

Here are the logs

The boot camp partition is unmounted prior to it being formatted, but something is still using it. I would look at anti virus or security software (or timemachine or other backup software) to see if it is preventing the unmount. I would also try the current Winclone 7 beta which has a delay of 5 seconds after the unmount.
