I've finally managed to get 6.14 working and on x11...
...and my software still crashes.
Looking further into this, I'm starting to feel that my problems revolve around my Nvidia graphics cards being a bit too old for Zorin 18. I'm starting to think this issue can not be solved and am wondering if I need to move over to a different distro - which would be very disappointing, since I really love using Zorin. 
Which nvidia card do you have and which driver do you use?
Did you test to go back to kernel 6.8 as your computer worked in Zorin 17?
You can also stay at Zorin 17, it will still be supported for one year.

Yes, You can use the Mainline Tool or when You are on Zorin 18, you should be able to install the Kernel over the Terminal because it is in the Repos:
Can You name the Model and what Driver You are use for it?

@Forpli, @Ponce-De-Leon - I have two GeForce GTX 780 cards installed
I ran this code in terminal to get information about it: lspci -k | grep -EA3 'VGA|3D'

I took a Look and it seems that You can use the 470 Driver for it. Is this Driver installed? When You look at the ''Additional Drivers'' Tab in Software & Updates is the Driver shown as installed?
Another Point about this Driver: I'm not entirely sure if this Driver is compatible with Kernel 6.17 or even the 6.14 Kernel. So, it is good that You still have the 6.8 Kernel installed.

For the 470 driver you need kernel 6.8. The installation will probably fail when you try it with higher kernels as 6.14 or 6.17.

Yes, I have 470 as an option:
So I'll run one of the two options here and switch back to kernel 6.8 and give that a shot
Please start first in the 6.8 Kernel and then use the Driver. Otherwise it could get Trouble.

Although I changed to kernel 6.8 before changing to the 470 driver, I still got this error message after the installation:
After restarting the machine, I checked and it was using the 470 driver. So I tried testing Krita and Unity and both appear to be stable now. Krita doesn't crash and the colours in Unity have returned to normal!
But of course it wasn't going to be a complete solution - one of my monitors have now stopped working! 
I've changed between the two 470 alternate drivers that was listed, and they're both producing the same error message above and both perform the very same on restart - with only one monitor working.
Did You switched to Xorg?
Maybe a Reinstall of the Driver could help. Do that in the Terminal when running the 6.8 Kernel. First uninstall all current Nvidia Stuff with
sudo apt purge nvidia* libnvidia*
and then type
sudo apt autoremove
to remove file Rests. But please take a Look at the List of removing Files before You delete them. Then to install the Driver type
sudo apt install nvidia-driver-470 nvidia-dkms-470

Thanks for persevering with this @Ponce-De-Leon I really appreciate your support.
Yes, it's now very clear that the alternative Wayland breaks my Wacom stylus so I'm keeping it in Xorg.
I'll follow your instructions here to remove and reinstall the driver and let you know how it goes 
I've followed your instructions @Ponce-De-Leon and it resulted in [what I assume is] the same error as when I installed 470 last time 
Errors were encountered while processing:
nvidia-dkms-470
nvidia-driver-470
E: Sub-process /usr/bin/dpkg returned an error code (1)
Could You post the whole Output of the Installation Process please?
I closed terminal and restarted the machine before seeing your latest reply - is there a way to recall the output? 
Simply repeat the Steps.

You were running in Kernel 6.17 and the Driver wanted to built for that but this Driver isn't compatible for this Kernel because it is too new.
That's really bizarre - last time I changed the kernel, I set it to use 6.8. I'll try to change it again to 6.8 and reinstall the driver again
Here is a guide how to set an older kernel to default:
After 6.8 kernel updates you should repeat this procedure.
