Storybook does not start

I have created react app with and create-react-app (and not made any changes in the app ) and initialized storybook by running npx sb init but running yarn storybook gives the following error. I have also tried this with nextjs but storybook gives the same error.

Answer

It seems that my Windows environment variables were messed up, after a fresh Windows installation everything seems to be working fine.
