Orphaned TPM-bound Entra Workplace Join device — no tenant access, backend deletion required

I have a personal Windows device that remains stuck in a TPM-protected Workplace Join to a former Microsoft Entra ID tenant.

I no longer have tenant access and am not an admin.

Local remediation completed:

- dsregcmd /leave executed as SYSTEM

- All MS-Organization / AAD certificates removed

- Device still reports WorkplaceJoined : YES

Azure Support ticket creation fails with:

AADSTS160021 – interaction_required

Application requested a user session which does not exist.

Tenant inaccessible / user not present in tenant.

This is an orphaned Entra ID device object. Requesting guidance or escalation for backend deletion.
