After updating to Cursor version 0.49.4 on Windows, I can no longer load chats that were created before the update. Chats created after the update load without issues.
This is a critical issue for me because I need access to past conversations for reference and ongoing work.
Steps to Reproduce
Open Cursor (version 0.49.4) on Windows.
Attempt to open a chat that was created before the update.
Observe that the chat does not load (see screenshot).
Same issue here on MacOS. However it happened after a normal System Reboot today, not when Updating Cursor. I had already updated Cursor yesterday to 0.49.4
Console Log also shows: “workbench.desktop.main.js:3091 [composer] No composer data handle found” (See attached logs)
Same issue here, it happened after a simple Cursor restart.

I went digging in Cursor a bit deeper and I’m seeing the same errors generate (with my own file paths) as LorisFriedal in this window upon trying to load any past chat:
I’ve already tried 1 & 2. I just tried 3 (renaming the two cache folders mentioned there as _backup) and restarting – no dice. After opening Cursor in that directory and looking for fixes there, I can see old versions of files (probably for changelog/checkpoint storage) but none of the actual chats – so I’m not sure where that’s stored.
After digging through the various User folders to try to find backups with the Auto-Cursor-Agent (and/or figure out if my chat files are corrupted) it seems like that might not be something that’s surfaced through Cursor automatically:
Same here. I’ve just lost all my past chats which I was reading. Can’t access to any of them after the update and system restart. Also, we should be able to access these chats on the cloud on the web browser version of Cursor.
