Ubuntu 20.04 won't boot in 5.8.0-63-generic

cn flag

I don't know how it happened, but most likely after updating the packages, I can no longer run 5.8.0-63-generic. After the loading animation, I just get a purple screen. I tried to press Ctrl + Alt + F1 or Ctrl + Alt + Delete after that I see my account and login screen for a second, after that the screen freezes and I cannot see the keyboard input. At the same time the screen resolution is rather strange like 640x480.

I tried to use Advanced options for Ubuntu after BIOS logo. I have 4 options:

Ubuntu, with Linux 5.8.0-63-generic
Ubuntu, with Linux 5.8.0-63-generic (recovery mode)
Ubuntu, with Linux 5.8.0-59-generic
Ubuntu, with Linux 5.8.0-59-generic (recovery mode)

First 2 options not working at all. In recovery mode I got this: screen

Then everything freezes and nothing happens.

In 5.8.0-59-generic option everything works fine. I tried to determine what happened after update and checked update list of packages: screen

Can somebody give me any advice to boot into 5.8.0-63-generic again?

Booted into 5.8.0-59-generic and installed ssh:

sudo apt update
sudo apt install ssh
sudo reboot

Booted into 5.8.0-63-generic and connected via ssh and then:

sudo apt purge nvidia*
sudo reboot

After reboot everything started working again. I was guided by this post: https://askubuntu.com/a/1129890/884692

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
