Hey, thanks for the report. This matches a known crash on macOS (code “5”) that the team is actively investigating.

Quick diagnostic questions:

• Do you have any MCP servers installed (Atlassian, GitHub, Supabase, etc.)?
• Does this happen in a new/empty project with a fresh chat?
• Can you open Cursor Settings → Network → Run Diagnostics and share any errors?

Try these workarounds:

• Disable extensions: launch from the terminal with cursor --disable-extensions
• Disable GPU: launch with cursor --disable-gpu (results vary for users)
• Check the console: before the crash, open Help → Toggle Developer Tools and review the Console tab for errors

Let me know what you find.
