It's due to accounts on the image having packages that are not "provisioned" - these are packages preinstalled which will deploy when a new account is created.
If you don't need that app, you can remove it with the below command in PowerShell:
Get-AppxPackage | Where-Object -Property Name -Like "*Microsoft.StartExperiencesApp*" | Remove-AppxPackage
Alternatively if you want to provision the package, there's the "Add-AppxProvisionedPackage" command, can look up documentation on that.
Ran into this quite a few times due to language packs etc. removing them usually resolves.
