React Native Built App is closing unexpectedly-CodePudding

Okay, I've been struggling for the last two days and this is it. I'm developing my first React Native android app using React Native CLI and using the following Packages:

"dependencies": {
    "@react-native-masked-view/masked-view": "^0.2.6",
    "@react-navigation/drawer": "^6.3.1",
    "@react-navigation/material-bottom-tabs": "^6.1.1",
    "@react-navigation/material-top-tabs": "^6.1.1",
    "@react-navigation/native": "^6.0.8",
    "@react-navigation/stack": "^6.1.1",
    "react": "17.0.2",
    "react-native": "0.67.3",
    "react-native-gesture-handler": "^2.3.2",
    "react-native-immersive": "^2.0.0",
    "react-native-linear-gradient": "^2.5.6",
    "react-native-material-textinput": "^1.3.0",
    "react-native-pager-view": "^5.4.15",
    "react-native-paper": "^4.11.2",
    "react-native-reanimated": "^2.4.1",
    "react-native-safe-area-context": "^4.2.1",
    "react-native-screens": "^3.13.1",
    "react-native-svg": "^12.3.0",
    "react-native-tab-view": "^3.1.1",
    "react-native-vector-icons": "^9.1.0"
  },
  "devDependencies": {
    "@babel/core": "^7.12.9",
    "@babel/runtime": "^7.12.5",
    "babel-jest": "^26.6.3",
    "jest": "^26.6.3",
    "metro-react-native-babel-preset": "^0.66.2",
    "react-native-svg-transformer": "^1.0.0",
    "react-test-renderer": "17.0.2"
  },

In the Development mode, The App works just fine and smooth. I'm developing the app without any errors. But, When I built the app for production into aab and apk files, the issue arises. If I run the app, whether via npx react-native run-android --variant=release or installing the app on my physical device, the app just close instantly after opening. Here's the

Please run the app in the simulator with LogCat running and check the error message there. That should give some indication, like this it could be anything. If logcat does not automatically run in your android studio you can open a terminal and run:

adb logcat

Okay. The problem was, in android/app/build.gradle, I've changed following values:

def enableProguardInReleaseBuilds = false

def enableSeparateBuildPerCPUArchitecture = false

universalApk false

If I keep those unchanged, the builds work perfectly and smoothly. Can anyone please describe the reason?
