Project does not save or export

Saving and exporting fail together far more often than either fails alone, because both depend on the same three things: a valid session, somewhere to put the result, and enough GPU memory to finish the work. Isolating which one is at fault takes one test each.

Symptoms

If one or more of these match what you are seeing, you are on the right page.

  • •Both Ctrl+S and the export dialog fail in the same session
  • •The sync indicator shows Sync Error and export stalls
  • •Everything works again after reloading the page
  • •The problem only appears on large compositions

Causes and fixes

Ordered from most to least likely. Work down the list — each cause is paired with what to do about it.

  1. 1

    The session has expired, so no write of any kind is authorised.

    Sign out and back in. This is the fastest test: if Ctrl+S succeeds afterwards, the session was the cause and export will work too.

  2. 2

    Storage is full, which blocks the save and leaves the export with no room for its output.

    Check the storage percentage in the account indicator. Remove unused assets from the Asset Library first — embedded images dominate project size.

  3. 3

    GPU memory pressure is stalling the export renderer.

    Export renders at full resolution regardless of preview quality. Reduce simultaneous blur, alpha mask and non-Normal blend mode usage, or export a short range first to confirm the composition is the limit.

  4. 4

    The browser went offline mid-session.

    Saves queue locally and resume automatically; exports do not. Restore connectivity, wait for the indicator to read Saved, then export.
