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:
