Checked the debug log of importing the OVA and noticed that the golden VM cannot start up due to the error as below.

VBoxManage: error: Because the USB 3.0 controller state is part of the saved VM state, the VM cannot be started. To fix this problem, either install the 'Oracle VM VirtualBox Extension Pack' or disable USB 3.0 support in the VM settings (VERR_NOT_FOUND)
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component ConsoleWrap, interface IConsole

Based from DDAN debug logs, we found the cause of the issue.

VBoxManage: error: Because the USB 3.0 controller state is part of the saved VM state, the VM cannot be started. To fix this problem, either install the 'Oracle VM VirtualBox Extension Pack' or disable USB 3.0 support in the VM settings (VERR_NOT_FOUND)


Recommenadations and actions:

1. The issue would be from the image wherein it uses the USB 3.0 Controller, and DDAN does not support it.
2. Please remove unnecessary softwares installed to avoid performance or FP/FN issue.
