looks like the problem is i nthe Cellar installation of Mono.
Try installing mono 6.6.0 from the official installer or set "omnisharp.useGlobalMono": "never"

Success! 🎉

Thank you @filipw that was indeed the issue!

So for completeness, these are the steps I took.

I downloaded version from the mono site (as I have Visual Studio for macOS also installed) and ran the installer.

I then ran source .zshrc from my terminal to refresh things followed by mono --version

So this is the version now installed globally.

I then restarted VSCode and 🎉
