Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
Today I opened several projects that were not touched for the last one or two weeks and realized chat window is stuck on “Loading Chat” indefinitely. It means I cannot see any previous chats I had with the AI. It’s quite frustrating because there were some work in progress. The editor also shows the error “[composer] No composer data handle found“ at the button left.
I’m not sure which update caused it but I had couple updates the last 2 weeks but I suspect it was the latest update (check my cursor version below).
Steps to Reproduce
Probably trying to open older (> 2 weeks ago) project with the cursor version I shared below.
Expected Behavior
To open the chat history without any issue.
