We're running into a similar issue with preact@next. Our structure is like this:

/subpackage1
  /package.json
  /dist/...
/subpackage2
  /package.json
  /dist/...
/dist
package.json

Only the top-level module can be required when linking via yarn link. Neither of the sub-packages will work. This is the code that triggers the error:

const { Component } = require("preact");
const { useState } = require("preact/hooks"); // imports "preact"
console.log(Component, useState);

And the error itself:

internal/modules/cjs/loader.js:605
    throw err;
    ^
