Reproduction

https://github.com/rnnyrk/tasks-sc

https://github.com/rnnyrk/tasks-sc/blob/main/src/components/modules/tasks/TasksOverview.tsx

Issue also happens with every component commented out and the only styled component being in the styled.div in the last file (TasksOverview)

Steps to reproduce

git clone git@github.com:rnnyrk/tasks-sc.git
cd tasks-sc && pnpm i
pnpm dev

Expected Behavior

I'm trying to get Styled Components working with React Aria + NextJS 14. Rendering the Styled Components as use client, so that shouldn't cause trouble. I expect the components to render without an error, since I'm not extending any component as the error suggests..

Actual Behavior

Component is not a styled component and cannot be referred to via component selector.

But I'm not extending any component. Codebase is rather simple, just a few styled components. Also downscaled to one rendering 1 component which is just a styled.div I get this error..
