Netlify CLI v23 errors out when setting up Edge Functions

[leereamsnyder]

Describe the bug

When I do netlify dev or netlify build, they fail on the Edge Functions setup

Here's the error output

Error: There was a problem setting up the Edge Functions environment. To try a manual installation, visit https://ntl.fyi/install-deno.

I have installed Deno manually as suggested in the error message and that makes no difference

Steps to reproduce

Run netlify dev or netlify build with Edge functions

Configuration

[build]
  command = "npm run build"
  publish = "build"

[build.environment]
  TZ = "America/New_York"
  TERM = "xterm"

[dev]
  framework = "#static"
  autoLaunch = false

[[plugins]]
  package = "netlify-plugin-checklinks"
    [plugins.inputs]
    skipPatterns = [
      '/auto-optimized-image', 
      '/resized-n-optimized-image', 
      '/index.html'
    ]

[[plugins]]
  package = "@netlify/plugin-lighthouse"

[[plugins]]
  package = "netlify-plugin-playwright-cache"

If anyone else see this, I was able to fix it this way:

• Stop any netlify-cli running processes
• Delete ~/Library/Preferences/netlify/deno-cli
• run netlify dev again, which will re-setup the Deno bits and appears to get things working again.
