After updating to this version, I found that the sidebar chat was missing, and these were all very large chats—chaps that involved changes to hundreds of code files at once—and these chats were from just a few hours before the update.
Steps to Reproduce
You might need to try making hundreds of changes to the model in one go within a single dialogue, then update to this version; you’ll find that the dialogue is missing.
Hey, this is a known issue. Large chats, especially ones with hundreds of file changes, are more likely to hit this after updates. Your data is probably still there, it’s just not accessible in the UI.
Here’s what to try:
Close Cursor completely (check Task Manager too).
Open %APPDATA%\Cursor\User\globalStorage
Look for files named state.vscdb.corrupted.1741... (the number will be different).
If you find one, rename the current state.vscdb to something like state.vscdb.old, then rename the .corrupted file to state.vscdb.
Also, make sure to update to v2.6.16 or later when it’s available for you. It includes a fix specifically for large conversations with many file changes.
The team is aware of this class of issues. Let me know if the workaround helps or if you need more guidance.
