Hi Tăng Nhật Đăng,
Thank you for reaching out to the Microsoft Q&A platform.
Based on your question, description we understand that you are unable to start the VM.
When you try to stop, start, restart, or redeploy an existing VM, the process fails, and you receive an "An unexpected error occurred while processing the network profile of the VM. Please retry later" error message. When this error occurs, the VM is put into a failed state.

Verify if there are any deny assignments in your Azure subscription that might be affecting your permissions. You can do this through the Azure portal by navigating to the Access control (IAM) section of your subscription or resource group.
Please check the activity logs to see if there are any unusual activities or security alerts that might have triggered the deny assignment. This can help you understand why the deny assignment was created.
