It happens because you changed the secure boot option, so you can normally boot your VM.
After the VM is up, you will be able to update your system and restart it. At the end, you can enable secure boot again. Of course, you will see again the error window on first boot, but the reason is still the same as before. Just boot the VM and that’s it.
