I followed this
https://www.bugpilot.io/guides/en/building-an-app-with-nextjs-and-electron-904b
but after packaging, only the electron app opens. Next js does not start. So the electron page is empty

"electron": "concurrently --kill-others \"next start\" \"electron index.js\""

Instead of the electron command I have this. This is the same as the start command, and it works
