Elementray OS 6 fails on installation

This one is interesting for me. Elementary OS 6 (Public Beta as daily snapshot (1 May 2021).

The installer process runs quite smoothly, however when it starts extracting the images, it get close to 60% (Both ISO's)
and then fails

I select British English for language, not to encrypt hard drive (Al though I have tried both).

If I select the show the terminal while installing the last entry is
DEBUG: "unsquashfs" "-f" "-d" "/tmp/distinst.eyr4fe9LHTVA" "/cdrom/casper/filesystem.squashfs"

However the moment I get to 62% the installation fails, repeatedly. with the following error.

Incidentally, when I then select try demo mode, and launch gnome web so that I can come here to report it, gnome web cannot browse the internet at all. No sites will load and simple reports and error.

I used the app center to install Firefox, and i can fully browser the internet

I though this could be a corrupt ISO but matched SHA256 the hash code is 100% on both beta and daily snapshot.

I hope this is helpful, not really sure what other possible information you would need
