I downloaded the Ubuntu 20.04 iso and made a boot running from it. Everything works normal. So I deduced that the problem is in updating third parties, something broke the video driver.
I did a new installation of Ubuntu 20.04 and its updates, installed my tools and lib required for my work.

It's working well so far.
Thank you for your attention and help.
