Hey!
That crash happens with very old “voice-only” projects – they don’t have the newer Settings/Voice schema the editor now expects, so the UI throws a Zod “expected object, received undefined” error as soon as it tries to read it.

Quick fix

Open the legacy converter:
https://creator.voiceflow.com/convert-voice-to-chat
Paste your project-ID link or upload the .vf export of 685142bb7494e98e7225dbea.
The tool adds the missing Settings object and re-saves the file as a current multimodal project.
Import the converted file (or just open the converted link) – you’ll now be able to open Settings and the Voice tab without the crash.

If you’d rather do it manually: export the old project (.vf), create a new blank project, then import that file – the new container automatically gets the up-to-date schema.

After conversion everything else in the canvas stays the same; only the broken Settings payload is patched.
