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:

<?xml version="1.0" encoding="utf-8" ?>
        <Profile Id="{75C4578C-D56D-402A-A946-CA3CCA60633A}">
                    <App DesktopAppPath="C:Windowssystem32mspaint.exe"/>
                    <App DesktopAppPath="C:WindowsSystem32notepad.exe"/>
              <![CDATA[<LayoutModificationTemplate xmlns:defaultlayout="" xmlns:start="" Version="1" xmlns="httsp://">
                      <LayoutOptions StartTileGroupCellWidth="4" />
                          <defaultlayout:StartLayout GroupCellWidth="4">
                            <start:Group Name="Group1">
                              <start:DesktopApplicationTile Size="2x2" Column="0" Row="0" DesktopApplicationLinkPath="%ALLUSERSPROFILE%MicrosoftWindowsStart MenuProgramsAccessoriesPaint.lnk" />
                              <start:DesktopApplicationTile Size="2x2" Column="2" Row="0" DesktopApplicationLinkPath="%APPDATA%MicrosoftWindowsStart MenuProgramsAccessoriesNotepad.lnk" />
        <Taskbar ShowTaskbar="true"/>
            <AutoLogonAccount rs5:DisplayName="Hello World"/>
            <DefaultProfile Id="{75C4578C-D56D-402A-A946-CA3CCA60633A}"/>

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?
