Cursor IDE constantly crashing

This is a known Windows issue where the renderer process hits a ~4GB memory limit (Electron limitation). There’s a similar thread with workarounds:

  1. Check for OTEL errors: Ctrl+Shift+P > Developer: Toggle Developer Tools > Console - look for [otel.error] lines
  2. Rotate chats: Start a new chat when the current one gets large (this was the accepted solution for another user)
  3. Monitor memory: Ctrl+Shift+P > Developer: Open Process Explorer to watch the renderer process
  4. Test extensions: Run cursor --disable-extensions from command line to see if an extension is contributing

If you see OTEL errors, consider downgrading temporarily to 2.3.34 from Download · Cursor and disabling auto-updates.
