I successfully created a bootable USB from all the AV option except the last one. The whole thing took less than 22 minutes.
I did the following:
reformatted the USB from explorer
selected all the AV ISOs except the last one
did a search for the USB and selected it.
made sure that direct extraction was selected
selected USB->create USB
The result ended in the following video:
