There are two issues here. I recommend focusing on the first one.
Here is a guide:
Please remember that you are likely looking for the 5.15 kernel, not the 4.15 kernel. So be sure to follow step by step reaching the Grub Menu and Advanced Options for Zorin to ensure you are booting into the correct previously working kernel.
As it was pointed out, my system is in the 5.15 dot something range. The first line I chose which was the first line that said Generic but as an earlier version did nothing and came back to the same Kernel issue. So what the heck, I went to the next and even earlier 5.15 version (so now the second oldest from the current one if that makes sense?) and chose its line ending in Repair.
That did the trick. I will now poke around following the suggestion that got me here to make any additional changes.
And because I'm crazy, I will then finally update to the latest Zorin release. In for a penny, in for a pound.
Thanks everyone and for now, lets called this FIXED (closed?) Stay well, PDC
