I also encountered a similar issue.

The CPU usage was ~100% and an error message was displayed like “this window is not responding” after a while.
I could fix it thanks to the post above,
- in the folder C:\Users{namePC}\AppData\Roaming\Cursor\User\workspaceStorage find your workspace and delete the file “state.vscdb”. then all chat history will be deleted and all files that were opened in the workspace will be closed too.
In my case of macOS, I did the followings:
- Go to the directory. On Mac OS, it is as follows.
cd ~/Library/Application\ Support/Cursor/User/workspaceStorage/
- Find the workspace directory.
grep $WORKSPACE_NAME */workspace.json
- Delete the file
rm <workspace-directory-name>/state.vscdb
rm <workspace-directory-name>/state.vscdb.backup
