My favorites and task switcher has vanished after I upgraded to 22.04LTS

I was using Ubuntu 20.04 LTS with Windows 10 on a dual booted PC. Today, around 2 hours ago, I have upgraded my Ubuntu using the sudo do-release-upgrade -d command. Everything worked like a charm and thankfully, I was even able to avoid the Grub 2.06 issue where it fails to detect any other OS that has been installed on that PC. Now that I have logged in on my Ubuntu 22.04 LTS, my dock is only showing the application button (screenshot attached) and all of my favorites have been vanished and I can't seem to access them at all. Even to switch between minimize apps, I have to use Alt+Tab key. On my 20.04 LTS, I got the dock by running the following commands:

First,

sudo apt-get install unity-control-center

Then,

gsettings set org.gnome.shell.extensions.dash-to-dock extend-height false && gsettings set org.gnome.shell.extensions.dash-to-dock dock-position BOTTOM && gsettings set org.gnome.shell.extensions.dash-to-dock transparency-mode FIXED && gsettings set org.gnome.shell.extensions.dash-to-dock dash-max-icon-size 49 && gsettings set org.gnome.shell.extensions.dash-to-dock unity-backlit-items true
