Why would squashfs fail on O/S install on my mini pc build?

I can’t get the logs from Fedora but have got log from POP O/S

DEBUG: “unsquashfs” “-f” “-d” “/tmp/distinst.EyPuvlWM4TPQ” “/cdrom/casper_pop-os_22.04_amd64_intel_debug_600/filesystem.squashfs”
ERROR: extracting error: archive extraction failed with status: exit status: 1
ERROR: errored while installing system: archive extraction failed with status: exit status: 1
INFO: Install error: archive extraction failed with status: exit status: 1

some more info here For The life of me I can not install a UEFI boot image of Linux on AM4 B550M-ITX - #7 by Milky_Pimms
