Similar problem here. Adding a .eleventy.js config makes the build fail. I guess there is an issue between "require" and "modules"

[11ty] 2. require() of ES Module /workspaces/app/.eleventy.js from /workspaces/app/node_modules/@11ty/eleventy/src/Util/Require.js not supported.

(Using Node v19.9.0 & eleventy v2.0.1)

Ok, I figured it out, the error happens when the package.json has "type": "module".
