### Describe the bug

Similar to: https://github.com/storybookjs/storybook/issues/19371

This only happens to one specific developer in our team, we have tried everything we can think of but we continue having this error in that specific machine.

### Additional context

In https://github.com/storybookjs/storybook/issues/19371 it seems that this was fixed in version 6.5.13, but we are using 6.5.13.

Seems edge case, since it's only happening in one of our dev machines. Could I kindly ask for advice on how to debug this, what to try to address this error please?

Thanks a lot in advance.
