So I've found the solution to this and sharing it here so if anyone going through the same can get help from this As the structure has changed a little in react native 0.70 we need to make changes in some extra files also So these are the changes which we need to make, i'ive used newApp but you've to use your package name there

In:android/app/src/main/java/yourApp/MainActivity.java:

package com.newApp

In:android/app/src/main/java/yourApp/MainApplication.java:

package com.newApp

In: android/app/src/main/AndroidManifest.xml:

package="com.newApp"

In: android/app/build.gradle:

applicationId "com.newApp"

In:android/app/_BUCK:

android_build_config(
 package="com.newApp"
)
android_resource(
package="com.newApp"
)

In: android/app/src/main/jni/MainApplicationTurboModuleManagerDelegate.h

static constexpr auto kJavaDescriptor =
  "Lcom/newApp/newarchitecture/modules/MainApplicationTurboModuleManagerDelegate;";

In: android/app/src/main/jni/MainComponentsRegistry.h

constexpr static auto kJavaDescriptor =
  "Lcom/yournewpackagename/newarchitecture/components/MainComponentsRegistry;";

In:android/app/src/main/java/yourApp/newarchitecture/MainApplicationReactNativeHost.java: make changes in these 4 lines

package com.newApp.newarchitecture;
import com.newApp.BuildConfig;
import com.newApp.newarchitecture.components.MainComponentsRegistry;
import com.newApp.newarchitecture.modules.MainApplicationTurboModuleManagerDelegate;

In:android/app/src/main/java/yourApp/newarchitecture/components/MainComponentsRegistry.java:

package com.newApp.newarchitecture.components;

In:android/app/src/main/java/yourApp/newarchitecture/modules/MainApplicationTurboModuleManagerDelegate.java:

package com.newApp.newarchitecture.modules;

after these steps just clean your project by typing this in your project terminal

cd android
./gradlew clean

now just go back and run your project and it would be a good approach to use android studio to run it for the first time
