Storybook: Module build failed (from ./node_modules/@mdx-js/loader/index.js)

[metamn]

Describe the bug
Everything worked fine until in and MDX file I've added a new story.
In other MDX files stories work fine.

The error message is:

Module build failed (from ./node_modules/@mdx-js/loader/index.js):
SyntaxError: Unexpected token (1:62)
