Hey @kien091, first off - you don't have reanimated babel plugin in your repro's babel.config.js Please follow Reanimated installation guide and make sure it is there. Let me know if it changes anything

@szydlovsky I am facing the same issue and this is my babel.config.js module.exports = { presets: ['module:@react-native/babel-preset'], plugins: [ 'react-native-reanimated/plugin', ], };

Hey @kien091 @Malik-Adil I think I got the fix and it is not connected to Reanimated whatsoever. The NDK version in your linked project is ndkVersion = "27.0.11718014", which is way too high for react native. Try changing it to, for example, NDK 23.
