Error Message on terminal while using Virtual Box to prepare in order to install Windows 10 in Mac OS(High Sierra)

I am trying to install Windows 10 in external SSD using Virtual Box. But in the initial phase I am stuck with the error while setup the virtual machine selecting the bootcamp.vmdk file.

Below are the commands and error details:

(base) SAIKAT-ceba:~ saikatbhattacharya$ sudo VBoxManage internalcommands createrawvmdk -filename bootcamp.vmdk -rawdisk /dev/disk2

RAW host disk access VMDK file bootcamp.vmdk created successfully.

One of the two will be used. Which one is undefined.

Request anyone to please advice how to resolve and proceed further. Is it good idea to install Catalina OS incase it is OS issue?
