Just to be clear.
You've cloned your old drive to a new ssd
It was booting past grub fine, but then locking up on log in
You've formatted the drive, created a new partition table, and made a fresh install of manjaro with the same result
Is that the chain of events so far?
what was the other distro you installed that booted successfully?
Can you post
inxi -Fxxxza --no-host
So we know more about your drive, and hardware in general.
