React native release build apk is not installing in real devices

I have an application which is currently running on react-native-cli Today I created a release build to test it in real device and build run successfully and got build from android/app/build/outputs/apk/release/app-release.apk

The issue is when I installed this apk in my mobile its showing app not installed?

Any idea why this is happening?

Here is my build.gradle file:

buildscript {
    ext {
        buildToolsVersion = "30.0.2"
        minSdkVersion = 26
        compileSdkVersion = 31
        targetSdkVersion = 30
        googlePlayServicesAuthVersion = "19.2.0" 
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:4.2.1")
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:4.3.10'
    }
}

allprojects {
    repositories {
        mavenLocal()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url("$rootDir/../node_modules/react-native/android")
        }
        maven {
            // Android JSC is installed from npm
            url("$rootDir/../node_modules/jsc-android/dist")
        }
        google()
        jcenter()
        maven { url 'https://www.jitpack.io' }
    }
}

project.ext {
  set('react-native', [
    versions: [
      // Overriding Build/Android SDK Versions
      android : [
        minSdk    : 24,
        targetSdk : 30,
        compileSdk: 31,
        buildTools: "30.0.2"
      ],

      // Overriding Library SDK Versions
      firebase: [
        // Override Firebase SDK Version
        bom           : "26.0.0"
      ],
    ],

Any suggestions will be helpful.

• I had tried allowing permission for untrusted apk in mobile
• Checked the memory space
• Verified the app is not installed before
