Answer 1

Same issue. I found this solution and it works for me

app.json configuration

"jsEngine": "hermes",
"ios": {
   "jsEngine": "jsc",
   "supportsTablet": true
},

and run project with npx expo start --localhost command

Answer 2

I can confirm that adding "jsEngine": "jsc" in the app.json under "android" and "ios", then RND will start working again.
