Invoke-PnPSiteTemplate: Object reference not set to an instance of an object.

I have a similar issue, @erwinvanhunen After creating a XML PnP-Sitetemplate with Get-PnPSiteTemplate and applying it with Invoke-PnPSiteTemplate I get an access denied error.

PS > Invoke-PnPSiteTemplate -Path ./CUSTOMER-Search-Center-Customization.xml                    
Invoke-PnPSiteTemplate: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
PS > Get-PnPException

Message          : Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
Stacktrace       :    at PnP.PowerShell.Commands.Base.PnPConnectedCmdlet.ProcessRecord() in c:\build\src\Commands\Base\PnPConnectedCmdlet.cs:line 93

My PnP Template is quite simple:

<?xml version="1.0" encoding="utf-8"?>
<pnp:Provisioning xmlns:pnp="http://schemas.dev.office.com/PnP/2022/09/ProvisioningSchema">
  <pnp:Preferences Generator="PnP.Framework, Version=1.11.2.0, Culture=neutral, PublicKeyToken=0d501f89f11b748c" />
  <pnp:Templates ID="CONTAINER-TEMPLATE-EC63A3A6533D4AA19F07FCA4F1106C96">
    <pnp:ProvisioningTemplate ID="TEMPLATE-EC63A3A6533D4AA19F07FCA4F1106C96" Version="1" BaseSiteTemplate="SITEPAGEPUBLISHING#0" Scope="RootSite">
      <pnp:SiteSettings AllowDesigner="true" AllowCreateDeclarativeWorkflow="true" AllowSaveDeclarativeWorkflowAsTemplate="true" AllowSavePublishDeclarativeWorkflow="true" SearchBoxInNavBar="Inherit" SearchCenterUrl="https://customertenant.sharepoint.com/sites/somesitecollection/SitePages/search.aspx" />
    </pnp:ProvisioningTemplate>
  </pnp:Templates>
</pnp:Provisioning>

I did set the custom script status with Set-PnPSite -NoScriptSite $false, but get the error anyway. Scripts are allowed on tenant level.
