"failed go start load apparmor profiles managed by snapd" while booting Ubuntu 22.04

I shutdown the laptop (Ubuntu 22.04) normally yesterday, and today when I tried to boot Ubuntu 22.04 it is not booting and giving me an error:

Somehow I went to root terminal and did following:

Then I found one solution on Ask Ubuntu (here) that is go to a root terminal and run following command:

sudo apt install apparmor-easyprof

It is giving me Unable to locate package apparmor-easyprof. I have tried to disable apparmor and then enabled it, but nothing worked for me yet.

How can I resolve this problem and boot my Ubuntu?
