Steam won't launch anymore on Zorin OS 16 Core

Ok, but I guess I would have to configure everything again.

In the future, is it therefore recommended for a low resource PC like mine to always choose the Zorin source rather than Flatpak when it is available?

Lets try with;

sudo apt install inxi
inxi -G

Ok, it is to try to resolve the driver issue?
First line done, I type the second...
