Hey, thanks for the report. This is a known issue, and it usually happens when there isn’t enough free disk space during an update.
Try restoring the chat history, the data might still be saved locally:
Windows path:
C:\Users\<YourUsername>\AppData\Roaming\Cursor\User\workspaceStorage\- Open the project subfolders and find
state.vscdbusing DB Browser for SQLite - Search for keys like
workbench.panel.aichat.view...orworkbench.panel.composerChatViewPanel... - Also check
C:\Users\<YourUsername>\.cursor\projects\<project_name>\agent-transcripts

For the future:
- Free up disk space before updates, this is the main cause of data loss
- Install the SpecStory extension for automatic chat backups
- You can postpone updates if you’re working on a critical project
Let me know if you manage to recover anything.
