react-native starting app errors on Android Studio

Title: Gradle build error: Could not find implementation class 'com.facebook.react.ReactPlugin'

Question:
I'm encountering an error while building my React Native project with Gradle. The error message states:

Could not find implementation class 'com.facebook.react.ReactPlugin' for plugin 'com.facebook.react' specified in jar:file:/Users/venkateshdasari/.gradle/caches/jars-9/410fa8799cd716bf29225aa40627be5f/react-native-gradle-plugin.jar!/META-INF/gradle-plugins/com.facebook.react.properties.

Additionally, the error mentions that the compileSdkVersion is not specified in my build.gradle file.

I have tried clearing the Gradle cache, deleting the specific cache files mentioned in the error, and invalidating caches in Android Studio, but the issue still persists.

Here are the relevant details of my project setup:

• React Native version: [your React Native version]
• Gradle version: [your Gradle version]
• Other relevant dependencies: [list any relevant dependencies]

I would appreciate any guidance or suggestions on how to resolve this issue.

[ React Native version 7.3.1 ] and [your Gradle version new ] with the actual versions you're using. Also, include any additional relevant information about your project configuration and dependencies.

I tried to create an app in Android Studio but it is not working throwing this error always:

Your Question is not very clear.

but still, from what I understood, you can try doing this step by step.

1. Check your android/build.gradle file:

<!-- begin snippet: js hide: false console: false babel: false -->

<!-- language: lang-js -->

buildscript {
    ext {
        buildToolsVersion = "30.0.2"
        minSdkVersion = 21
        compileSdkVersion = 31 // make sure this line is present
        targetSdkVersion = 31
    }
    }

<!-- end snippet -->

In your `android/app/build.gradle`:

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

 android {
    compileSdkVersion rootProject.ext.compileSdkVersion // This line must be added if it is not there
    }

<!-- end snippet -->

2. Do the following:

> Delete node_module folder and package-lock.json file
> from your root directory.
>
> Go to android folder and delete .gradle folder.
>
> Go to Android Studio ===> Build ===> Clean Project
>
> select File ===> Invalidate Caches ===> check clear system files and local history

this will restart the android studio

> 3. Go to terminal
> in your Root project, enter command : npm i --save
>
> after that, cd android; ./gradlew clean; cd .. //this will clean gradle files
>
> then run, npx react-native start --reset-cache
>
> after that, run npx react-native run-android
