Removing the commented line

// export default {

solves this. But why does a comment cause it?

I have no idea what's exactly causing it but the error seems to come from vite and no error happens in the SFC playground. You should open an issue there instead. It's weird that removing it seems to solve it while still allowing to add it again without crashing.

Took me a while to figure out: because of node_modules/.vite/ cache

@mariusa Have you solved it? I encountered just now, - - er. remove the comments . 3Q

Should have been fixed in vite: https://github.com/vitejs/vite/issues/4598
