Hey, thanks for the report. This is a known issue. The chats are still in the DB, but they don’t open because of DB issues. Your data is most likely not lost, the DB just can’t read it.
Try this:
Step 1: Check for corrupted files
- Fully close Cursor (check Task Manager)
- Open
%APPDATA%\Cursor\User\globalStorage - Look for a file like
state.vscdb.corrupted.1767...(the numbers will be different) - If you find one, rename the old
state.vscdbas a backup, then rename the corrupted file tostate.vscdb

Step 2: If there are no corrupted files
Can you share a screenshot of what’s inside globalStorage and workspaceStorage\[your-project]\? Sometimes the data is there. In a similar case, recovery via DM helped: Can't load or click on chats
About the “agent stream can’t started” error
This is usually related to Extension Host or network issues. If it happens often:
- Try disabling extensions temporarily
- Check if you have a proxy or firewall that might be blocking it
Important: This often happens when there’s not enough free disk space during an update, so the DB migration can’t finish properly. Please make sure you have enough free space before the next updates.
The team is aware of this issue and is working on a more reliable fix for chat persistence. Let me know if these steps don’t help and we can dig deeper.
