Hey, thanks for the report.
Short version:
- Chat history is stored locally and isn’t synced to the cloud:
%APPDATA%\Cursor\User\workspaceStorage - After crashes/updates old chats may stop showing. Without a backup, recovery is usually not possible
What to check now:
- Make a backup of
%APPDATA%\Cursor\User\workspaceStorage - When you click one of the missing chats, open Help > Toggle Developer Tools > Console, take a screenshot of the red errors, and share it here
Useful thread with options and discussion:
- If chats are stuck on “Loading Chat,” what to collect and where to look: Chat stuck on “Loading Chat” — cannot access previous conversation
I also recommend exporting chats regularly and considering SpecStory for auto‑backups.
