@samuelstroschein Yeah npm also crashes for me.

@segunadebayo @anubra266 running the dev server with pnpm works for me too. running the dev server with npm leads to the crash. I’ll investigate further. Zag does not seem to be the root cause.

Could someone confirm whether running the reproduction with npm run dev crashes?
