After upgrading to the latest version, the original project would crash when opened

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The original project of mine might have had overly lengthy historical dialogue sections, with approximately 4 days’ worth of content.
I can open other projects normally, but whenever I try to open my original project, the entire Cursor IDE crashes and exits completely. There are no any prompts.
I suspect that the long historical conversation caused the system to crash. How should I solve this now? Maybe renaming the project will enable me to access it. I want to know where the conversation history of the project is stored. I also want to clear it up.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. Workspace storage can get corrupted because of a large chat history. Good news, there’s a proven workaround.

Easy fix (you’ll lose chat history for this project):

  1. Fully close Cursor
  2. Open in Finder: ~/Library/Application Support/Cursor/User/workspaceStorage/
  3. Find the right workspace folder (you can sort by “Date Modified”, it should be the most recent one)
  4. Delete state.vscdb and state.vscdb.backup
  5. Reopen the project

If you want to keep your chat history, there’s a more advanced SQL fix in this thread: “Open Chat as Editor” causes permanent black screen when reopening project - #10 by satriowputra
It uses a Python script to remove only the problematic data while keeping your chats.

Let me know if it doesn’t help.

I found the corresponding project’s directory located at ~/Library/Application Support/Code/User/workspaceStorage/xxx and deleted it completely. However, when I opened it, it still reported an error and got stuck at the page where it prompted to upgrade and then exited.

Now I can just rename the folders. But this is a very serious problem. I don’t want to change the names of my folders.
