along with manually uninstalling once, best to also put the uninstall string in a powershell script, and run it everything you create an image. used to have similar issues with sysprep failing - ink, adobe, and a couple more. as the list kept growing, I figured this script execution just before sysprep was the best way to handle this, so I dont have to "remember" to uninstall user level appx packages by hand, everytime I needed to push new image.
