Batch process-set-removal-time never starts

Hi,
I’m want to set the removal time for historic process instances. I’ve created the batch with the REST API.
POST to http://localhost:8080/engine-rest/history/process-instance/set-removal-time with this body:

{
    "historicProcessInstanceIds": [ 
        "abc93eca-420d-11e7-9387-005056913512"
    ],
    "hierarchical": true,
    "absoluteRemovalTime": "2023-08-10T00:00:00.000+0000"
}

I can see the batch job in Camunda Cockpit but it never starts and progress is at 0%.
Can anybody help me?
Regards
Andreas

I have same issue. Is this resolved already?

It’s been more than a day since the Job is running in Camunda but the progress still 0%.
