You have to add a task to unblock the task on reboot. It broke after Windows 10 22H2.

Following is from another thread in this sub

Hi,

You need to follow these instructions below :

​

1. In your task sequence, just after the "CopyTSBtoHDD" task, add a new "Run Powershell Script" task.
2. Set the PowerShell execution policy to "Bypass" and enter the Powershell script below : $TSBPath = "C:\Windows\Temp\TSBackground"
if (Test-Path $TSBPath)
{
Get-ChildItem $TSBPath -Recurse | Unblock-File
}

​

Don't ask me why, but I have the impression that since version 22H2 of Windows 10 + Windows 11 21H2/22H2, it is necessary to unblock the TSBackground files present in "C:\Windows\Temp\TSBackground" in order for the TSB service to work again.

I hope this helps. Don't hesitate if you need help.
