"vite-plugin-react can't detect preamble. Something is wrong." when using styled-components

Describe the bug

When I’m rendering a styled component, I get the following error: “Uncaught Error: vite-plugin-react can’t detect preamble. Something is wrong. See https://github.com/vitejs/vite-plugin-react/pull/11#discussion_r430879201”

Reproduction

When creating a new project I don’t run into this problem. However, I’m trying to integrate vite into my existing project. Everything seems to work fine, but when I render a styled-component it crashes.

• Operating System: macOS Big Sur
