Error applying provisioning package for multi-app kiosk

I am setting up a multi-app kiosk in audit mode on a fresh install of Win 10 IoT Ent LTSC 1809.

I've create an XML assigned access file based on: https://learn.microsoft.com/en-us/windows/configuration/lock-down-windows-10-to-specific-apps

<?xml version="1.0" encoding="utf-8" ?>

                ]]>

        </Config>
    </Configs>
</AssignedAccessConfiguration>

I've then used ICD to create a provisioning package using this XML file. When I try applying the package, I get an error and the following event log:

ProvXML category 'UxLockdown' failed with '0xC00CE223' at CSP node 'AssignedAccess/Configuration'. Provisioning failed

From researching this error online, there may be an error in my XML file. I've gone over it a few times and validated against the schema but still getting this error.

Can anyone provide help?

change xmlns="https://schemas.microsoft.com/AssignedAccess/2017/config" xmlns:rs5="https://schemas.microsoft.com/AssignedAccess/201810/config"

to

xmlns="http://schemas.microsoft.com/AssignedAccess/2017/config" xmlns:rs5="http://schemas.microsoft.com/AssignedAccess/201810/config"

its http not https, yes M$ had me running around in circles on this one
