My Zorin when bad for some reason, which I was unable to determine. Instead of reinstalling it from fresh, I installed Linux Mint 20 Cinnamon. But, so I can be helpful here, I got my old Dell Inspiron 14Z Ultrabook and put Zorin OS 15.3 Core on there. This will allow me to help others on here when I can. Hope that is ok with everyone.
Hope your 2021 is starting out somewhat better than 2020.
