Failed to create object ID in Intune for new onboarded device.

We are deploying Defender for Cloud with XDR onboarding. We are implementing Defender policy with Intune enforcement setting, everything is working for 98% of devices as well. But, for some devices like Arc enabled machines, after going through each step and Microsoft troubleshooting documentation. Some devices are not able to create the synthetic object in Intune to receive Defender XDR policies. No solution is provided in the documentation or in MDEclient parser.

In the onboarding workflow, the synthetic object is normally created to apply the policy via Intune. But, when a device fails this process, we have no solution even after re-onboarding.
