Looks like addon-docs has its own dependency on react-element-to-jsx-string and allows all patch versions under v14.3.x, but the latest patch version has a bug which blows everything up.

Not sure if I should close this or leave for posterity

Figured out the fix for this. The issue isn't Storybook proper but rather configuration for Vite Storybook
