This has been happening to a lot of people and at least once a week to twice a week, someone posts this issue on the forum.
It's a fault of Software store containing Snap Store. Ubuntu Software Store most resembles the Windows Store, so on the surface, seems a good fit for Zorin OS.
But it is also true that the Software Store is buggy.
You can try
sudo apt install --reinstall gnome-software
And see if that resolves the error.
I recommend just using Synaptic Package Manager:
sudo apt install synaptic
