Does this stop you from using Cursor

No - Cursor works, but with this issue

Thanks for reporting this. This looks like a known data corruption issue with chat history.

However, since you mention that you can still find your history in the SpecStory extension, you can still use those backups, even if they don’t load in Cursor’s interface.

To avoid this in the future:

  • Regularly export important chats (three dots at the top of the chat → Export Chat)
  • Keep using SpecStory for automatic backups
  • Make sure you have enough free disk space before updates (low disk space is the most common cause)
  • Consider disabling the Agent Window beta feature if it was enabled

New chats should work normally.

You have been aware of the problem for at least three months. Why does it still exist?

can we do something to avoid this happen again? chat and project history security are most important things

my workspace and my history still here.

but don’t shows in my curosr.

it’s any chance to get it back?

Thanks for the extra info and the screenshots. Since your workspace files and history are still on disk, there’s a chance we can recover them.

Quick question: did you recently move or rename your project folder or workspace? If yes, move it back to its original location and restart Cursor, this should restore your chat history.

i aint do this.
can i install cursor to another disk and let these files back.
but and i wanna install an older version .where can i find it ?
