Hello Here is the solution. go to android/app/build.gradle and search for the line

project.ext.react = [
    enableHermes: false,  // clean and rebuild if changing
]

change this to

project.ext.react = [
    enableHermes: true,  // clean and rebuild if changing
]

and in MainApplication.java file add these two line to the top

import com.facebook.react.bridge.JSIModulePackage;
import com.swmansion.reanimated.ReanimatedJSIModulePackage;

and add this function

@Override
protected JSIModulePackage getJSIModulePackage() { 
      return new ReanimatedJSIModulePackage(); 
    }

Here is the screen shot

in the bable.config.js file add these ,lines like this

module.exports = {
  presets: ['module:metro-react-native-babel-preset'],
  plugins: [
    "react-native-reanimated/plugin",
  ],
};

and index.js

import 'react-native-gesture-handler'

After this clean your project, uninstall from the device and build it again. Cheers!!

Step 1:- go to android/app/build.gradle

project.ext.react = [enableHermes: false,] // update here true

Step 2:- go to android/app/src/main/java[Your Packages]/MainApplication.java

    import com.facebook.react.bridge.JSIModulePackage;
    import com.swmansion.reanimated.ReanimatedJSIModulePackage;
    
private final ReactNativeHost mReactNativeHost =
      new ReactNativeHost(this) {
...
    @Override
    protected JSIModulePackage getJSIModulePackage() { 
          return new ReanimatedJSIModulePackage(); 
        }
};

Step 3:- go to bable.config.js

module.exports = {
  ...
  plugins: ["react-native-reanimated/plugin"],   //add this line
