In this thread another user had the same problem with an integrated GPU from the same time. I'm wondering if some ideas from the thread there coud help you:
Unfortunately there is not marked a solution.
Maybe an older kernel could help as Aravisian suggested there?
You could install the mainline installer tool and install the 6.8 kernel to test. Then reboot and at "Advanced options for Zorin" in grub menu select kernel 6.8.
If it works you could set this kernel as default to boot or install Zorin 17 which is still supported and is based on this kernel.
I see in your screenshot that you use Wayland. Please test if it works better with Xorg. Logout and at login click on your username then a cog wheal appears at the bottom right corner.There select "Zorin Desktop on Xorg". But probably this doesn't effect the black screen.
