How can we reproduce the crash?

All I did was create a React project with a Shadcn + TailwindCSS template using bun init, and made minor changes to src/App.tsx (e.g. removing logos, changing text). It crashes during every second reload.

oh no: Bun has crashed. This indicates a bug in Bun, not your code.
