If you have added system76 repository to install Popsicle, then advise you remove that now you have installed Popsicle. There have been at least one case of PopOS updates messing up ZorinOS due to that.
It looks like you have a Pop-OS repository added in your sources.
I am sorry @zGnOmaha , I failed to spot this in the very screenshots you posted...
Since you must have added the repository at some point, that is what caused the partial upgrade to happen.
It just replaced your Zorin OS desktop.
What you might try if this was not your intention:
Remove the POP-OS Repository using `Software & Updates~ > "other software"
Once done:
sudo apt install --reinstall zorin-os-desktop
Add the pop repo:
sudo add-apt-repository ppa:system76/pop
Then you can install:
sudo apt install popsicle popsicle-gtk
Remove the pop repo when finished:
sudo add-apt-repository --remove ppa:system76/pop
