[Bug]: `Cannot convert object to primitive value` when passing Modules in args

[JReinhold]

Describe the bug

When passing a Module to an arg in a CSF story like this:

import { Description } from './Description';
import * as DefaultButtonStories from '../examples/Button.stories'; // 👈

const meta = {
  component: Description,
};
export default meta;

export const OfMetaAsComponentComment = {
  args: {
    of: DefaultButtonStories,  // 👈
  }
};

The story crashes with Cannot convert object to primitive value:

Cannot convert object to primitive value

Additional context

This is not a problem if the arg is defined in the meta, only in the story.
