try the steps below:
Verify and Enable Azure Disk Encryption: Make sure that the "Azure Disk Encryption for volume encryption" feature is enabled. If not, enable it. This feature ensures that all data stored on Azure disks is secure. After enabling it, save your changes and try to start the Virtual Machine (VM) again.
- Redeploy the Virtual Machine: If the previous step does not resolve the issue, consider redeploying the VM. This will create a new instance of your machine on new server hardware in Azure, which can help solve intermittent or hard-to-diagnose issues.
3.Confirm the Validity of the Secret in the Key Vault: Ensure that the secret you are trying to access in the Key Vault is within its expiration period. If the secret has expired, you will not be able to access it, which can cause the error. You need to renew or extend the validity of the secret to continue accessing it.
