Shopify run dev CLI error - Cannot read properties of undefined (reading 'forEach')

[kulit]

Hello,

I'm having error running my npm run dev scripts. It was running fine at first, and then I ran new extension for checkout ui, after that it crashes everytime I run it. I tried running it with -- --reset and tried reinstalling CLI with no luck.

When running --verbose
query FindApp and query allAppExtensionRegistrations was the last few queries being made.

Im running macOS and node version 18 CLI version 3.53.1

Having the same issue. But for me to recreate, I created the app with "npm init @Shopify/app@latest" and for get started building your app, instead of the remix option I chose Start by adding your first extension. Once I try to run npm run generate extension it throws me that same error.
