Is it too early to open issue about VSCode LSP? As you consider it still a prototype, sorry, if it creates useless noise, feel free to close it then, if it's not relevant yet.
(was not too sure, because in the README, it says "prototype: proof-of-concept only; do not log bugs")

It's not, no. Thanks for the issue.

I'm also seeing a similar error in a NextJS project. Happy to provide more details if needed!

Same for me, the only hint i can give in a nextjs project, with
next-intl/serverlibrary, it crashes with the above errorahejlsberg commentedon Jun 16, 2025
This appears to have been fixed. Closing.
