The build message "There was a problem setting up the Edge Functions environment" is indeed not very helpful, and the corresponding message during deploy also leaves room for improvement:

I am running netlify-cli in a docker container on a Mac M1, hence the aarch64. For those doing the same, it could be helpful if the error message reminded them about what architecture and platform they're actually running; Like in my case, the problem is Deno for Linux only have an executable for x64, not aarch64.

Perhaps not: The netlify-cli still fails build with edge functions on a Mac M1 even when running the docker container with platform: linux/amd64

Fixed in netlify/build#6708. Releasing soon.
