React Storybook cannot load in IE11

[helabenkhalfallah]

Describe the bug
I just started a new storybook project using npx sb init and webpack-react.
I have this issue on IE11 :

To Reproduce
I don't have any special code, just the default generated repo (without any change).

System

Environment Info:

  System:

    @storybook/addon-links: ^6.4.7 => 6.4.7

Additional context
I tried some solutions like :

• disable @storybook/addon-essentials.
• adding https://storybook.js.org/addons/@storybook/addon-ie11.
• disable FAST_REFRESH.

However the issue still the same.

Thank you for your help :)

Try removing Introduction.stories.mdx from the bundle. There's a known issue where MDX breaks IE11 compatibility
