This is due to a regression in the 5.13 kernel affecting Ryzen AMD cards.
Roll back to the 5.11 kernel and boot, and that should resolve the issue.
Tap esc or tab at boot up until you see the Advanced Options for Zorin menu.
Arrow key down to Zorin 5.11.0.... Kernel.
Hit Enter.
If that passes testing, you can set that kernel as default to boot from.
