It's an issue with intel microcode.

I know it's arch, but arch generally has amazing guidance even for different distros.
Considering the first error is "please update microcode"... Probably an intel microcode issue.
And the error mentions version of 0x22.
Googling found this:

Which suggests that a 4th gen desktop intel can be updated to 0x28. I think?

Updating microcode. Probably want to launch a less specialised LiveUSB. Considering TrueNAS scale is Debian, might as well use a Debian liveUSB disk
