VF project loads indefinitely
One project won’t open. I’ve tried different browsers, incognito, clearing cookies/cache, the whole deal. Every other project I try opens fine. To my knowledge there isn’t a function within this project that doesn’t exist in any other, but that’s the only thing I can think of. Would duplicating the project be worth trying at this point? Or downloading the .vf file and reuploading?

Here are a few things you can try when a single Voiceflow project gets stuck on the loading spinner while every-thing else opens normally:
1️⃣ Duplicate the project inside your workspace
• From the dashboard, open the ••• menu on the project tile → Duplicate.
• The copy is rebuilt from the latest saved version and often skips over whatever is blocking the original.
• If the duplicate opens, you can safely archive the broken one. 2️⃣ Export → re-import the .vf file
• In the ••• menu choose Download (.vf) (or use the Project API’s “Fetch Project” endpoint¹).
• Back on the dashboard press New project → Import (.vf) and select the file.
• This recreates the project from the raw JSON, which can clear hidden corruption or a bad asset reference. 3️⃣ Remove heavy/unused assets (if the copy opens)
Large images, videos or very long JSON payloads can occasionally cause long load times. Delete or compress anything unusually large, then press Run or Publish so the lighter version is saved to future downloads. 4️⃣ Basic browser resets (already done)
Hard-refresh (⌘/Ctrl-Shift-R) and clearing cache/cookies are the right first steps – since other projects load, the issue is inside that one project’s data, not your browser. If none of the above work and the .vf file itself will not import, the file is likely corrupted beyond what the UI can fix. In that case the best next step is to restore from an older backup if you keep them, or rebuild from a duplicate that last opened successfully. — ¹ Docs for exporting projects: https://docs.voiceflow.com/reference/fetch-project
