I'm not sure of your particular setup, but I'm betting the above should be "5A83-06BE" or "96D484DED484C24B".
You'll just have to figure out which partition Zorin OS is booting from, and substitute that UUID for what is in there now.
If it is actually on /dev/nvme0n1p7, then about the only thing you can do is reinstall, since something is broken on that partition that won't let it boot.
Do a backup first if you've saved any personal files in the directories provided by Zorin OS. I recommend not using those, instead using directories on an external drive for your personal files. Or bind-mounting those Zorin OS-provided directories to redirect to directories on an external drive.
That way, you can completely wipe the OS drive(s) if you wanted, and your personal files aren't touched.
