web-streams-polyfill package interfering with nextjs api routes

[Ortieez]

When installing this package because of react.email recommendation (needed to polyfill web streams for safari) for the render function they offer.

When installed into nextjs project this happens:

Ways to reproduce:

• create default nextjs project using their website

• install this package

• import the package into the page.tsx (put "use client" on top)

• and write a simple api route

• call the route in page.tsx

• gets the error
