Fascinating...
ok only run

sudo dpkg --configure -a

Post the output, if any... if none, proceed to run:

sudo apt --fix-broken install

And post the output here.

Also, have you ever installed a Higher Linux Kernel than what is supplied by Zorin?

No, I Have not. An Update Pop-up today did this wonderful thing.
Actually I also found .46 and .48 according to the output for @ghostminator's command.

The quote tag is not closed on the above line. Please correct this by adding the " at the end of that line.
It should look just like

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=<731d98ad-46a5-4095-87c7-8bdb>"

Once done,
ctrl+x then the y key, then the enter key.
Then run

sudo update-grub

I am Sorry the Output Was not copied Out of the Page it was Closed.

Ok, how about the full contents of:
/boot/grub/grub.cfg
?

How to Copy the Entire thing?

Don't use nano. It can be done but is a pain...
Instead, just open it with text editor.

Line 184 is:

linux /boot/vmlinuz-5.15.0-46-generic root=UUID=731d98ad-46a5-4095-87c7-8bdb28065344 ro quiet splash $vt_handoff

Which is also in your grub default.
I think you added that to enable Hibernate... (Is hibernate working?)
But let's Temporarily test something...

sudo nano /etc/default/grub

and revert
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=<731d98ad-46a5-4095-87c7-8bdb>"
To
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
ctrl+x, y, enter...

sudo update-grub

Then test.

Also, Is there any way to stop that pop up from coming, I can live with sudo apt update. It is a real challenge to keep your Linux alive evryday without re installation :joy:
The pop up is back :scream:
