RuntimeError in load_payload

Hello,

I always get the following runtime error:

What I'm doing wrong?

I'm using fireiso v1.0.0 and trying to root my fire tv stick 4k from Amazon. I've booted the iso in a VirtualBox environment, if it is important. What can I do?

unless it's a hypervisor level VM, it might not work with your host OS.

Have you tried to boot the ISO natively? as in - burn .ISO to CD/DVD/USB and boot to it via the BIOS/UEFI menu, otherwise that looks to be a problem with the actual payload, if it'd be python v2/v3 conflict it wouldn't go as far as it did

this might help anyone else having similar problems in the current year of our Lord 2021
