Reacls for a device keep failing with the following error message:
"ReACL failed System.NullReferenceException: Object reference not set to an instance of an object"
You can also find this in the logs:
"Skipping irrelevant User Profile folder ''
This means that there is a profile in the ProfileList reg key that is missing its ImagePath
This profile may look fine in the user profiles stored in this computer but its missing required registry keys.
You will need to find the registry keys on the device and clear them and the profile before trying another ReACL
