Don't APFS format your usb (?) keep it as HFS+ as @0403979 suggested.
Is the machine you are upgrading APFS?
Yes all HFS+. both systems are HFS+.
Tried APFS installer once just to see if it makes any diff.
I just tried again with 20G SSD installer with b12 patcher same result, crash once select language.
