Issue with Hot Reload and Remote Component Re-Import breaking app

[whatisphp]

Describe the bug

I’m using the module-federation-enhanced example from the rspack-examples repository. When I run the application as provided in the example, it works correctly.

However, I encountered an issue during development when I temporarily removed the usage of the remote component ProviderButton in consumer/src/App.tsx. Here’s what happened:

Initial Code (Working):

The App.tsx originally looked like this, and the app worked fine:

import './App.css';
// The remote component provided by federation_provider
import ProviderButton from 'federation_provider/button';

const App = () => {
  return (
    <div className="content">
      <h1>Rsbuild with React</h1>
      <p>Start building amazing things with Rsbuild.</p>
      <div>
        <ProviderButton />
      </div>
    </div>
  );
};

export default App;

Temporary Change (Hot Reload Worked):

I modified the code to remove ProviderButton like this:

import './App.css';
// The remote component provided by federation_provider

const App = () => {
  return (
    <div className="content">
      <h1>Rsbuild with React</h1>
      <p>Start building amazing things with Rsbuild.</p>
      <div>
      </div>
    </div>
  );
};

export default App;

When I saved the file, the app hot reloaded, and the button disappeared as expected.

Reverting to the Original Code (Error):

After reverting the code back to its original state (re-adding the ProviderButton import and component usage), I saved the file, but this time I got the following error:

Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: object. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Check the render method of `Page`.

It seems like something breaks in the module-federation-enhanced setup when hot reloading after the ProviderButton component is removed and then re-added. Any idea what might cause this issue and how to resolve it?

Both @module-federation/rsbuild-plugin and @module-federation/enhanced/rspack gives same error.

When app crashes

lazy(() => import("...").then(m => {console.log({m});return m;}))

returns empty m.default instead of function
