Try clearing the build cache and node modules:

cd android
./gradlew clean
cd ..
rm -rf node_modules
npm install

Downgrade to react-native-reanimated to version2.17.0:

npm install [email protected]

If the above suggestions don’t work, then you’ll have to include the versions of react-native and react-native-reanimated you’re using in your question. The error suggests a potential version mismatch between both packages. Hope this helps!

EDIT I:

Alternatively, try installing react-native-reanimated 3.6.1 instead:

npm uninstall react-native-reanimated
npm install [email protected]

Then clean and rebuild:

cd android
./gradlew clean
./gradlew assembleDebug

EDIT II:

Check if your babel.config.js includes the following:

module.exports = {
  presets: ['module:@react-native/babel-preset']
}

Fix node version - downgrade to Node 18:

nvm install 18
nvm use 18

Clean and rebuild:

rm -rf node_modules
npm install
cd android
./gradlew clean
./gradlew assembleDebug

If the error persists, let me know.

I have already tried to clear the build cache and node modules, but the problem is still present. here are the versions I use "react": 18.2.0", "react-native": "0.74.3","react-native-reanimated": "3.15.3"
