Installation: Input/Output error in GParted and Firefox and possibly others

/usr/bin/gparted: line 221: /usr/lib/gpartedbin: Input/Output error

Starting Firefox gives back an Input/Output error… So, I cannot post the logs…

What shall I try next?

Here some template to start your post:

Please send installer logs if install fails, it is the only way for us to solve issues with your hardware and setup situations!
there is also an easy to use log tool on the panel of the ISO (live installer)

installer log from live session:

cat /var/log/endeavour-install.log | eos-sendlog

Hardware information:

inxi -Fxxc0z --no-host | eos-sendlog

Boot log:

journalctl -b -0 | eos-sendlog

run the commands and share the short-url in your post.
