Hey there,

Firstly, your project isn’t gone. This “Blob not found” error is a server-side issue on our end, not a problem with your machine, network, or cache, so clearing caches, reinstalling, or updating won’t change it. What’s happening is that one specific chat’s saved state points at some stored data we can’t retrieve anymore, so every message you send in that chat fails.

The catch is that the affected chat can’t be resumed. The reliable way to keep working is to start a new chat in the same project. New chats don’t reference the missing data, so they work normally. If you want to carry context over, just paste in or briefly re-summarize the key points from the old one.

This is a known issue our team is actively working on. Since it’s server-side, it’ll be resolved with a fix on our end (nothing to update on your side), though I’ll be upfront that it hasn’t fully landed yet.

If a brand-new chat also fails for you, let me know here, that would point to something a bit different and I’d want to dig in.
