Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, this is a known issue. The composer.composerHeaders key in local storage can grow and crash the chat panel. After it crashes, the data stays corrupted, so the chat won’t open anymore.

Workaround:

1. Fully close Cursor
2. Open a terminal PowerShell or CMD and run:

sqlite3 "%APPDATA%\Cursor\User\globalStorage\state.vscdb" "DELETE FROM ItemTable WHERE key = 'composer.composerHeaders';"

3. Start Cursor again

If sqlite3 isn’t installed, you can just rename state.vscdb to state.vscdb.old in the same location %APPDATA%\Cursor\User\globalStorage\. This will reset some settings, but chat should work again.

The chat history sidebar will be empty after this, and chat history won’t be available, but it should unblock you so you can keep working.

The team is aware of this bug. Let me know if the workaround didn’t help.
