Did You received a Kernel Update to Version 7.0? IF yes, try it with switching back to the older 6.17 Kernel on the GRUB Menu with choosing there ''Advanced Options'' and then take the 6.17 Kernel Option without the Recovery Mode.

Also: Are Secure Boot and Fast Boot in BIOS disabled? Does Your System runs in Wayland or X11? You can check that with the Command echo $XDG_SESSION_TYPE via Terminal.

Boot with the older kernel (via advanced options for Zorin) and then edit the grub file:

still booting to the newer version when restarted

Do you have booted into the old kernel when you edited the grub file, and did you run 'sudo update-grub' afterwards to apply the changes?

i didn't run sudo update -grub after editing. but ran into the newer kennel after editing the grub file on reboot.

sudo update-grub is important. When you don't run that, it doesn't work and you boot with the latest kernel by default.
