How can I fix the Keystore file not found for signing config 'debug' error?

I'm trying to setup a new react-native project but I ran into this error when I tried react-native run-android:

What went wrong:Execution failed for task ':app:validateSigningDebug'.> Keystore file 'C:\Users\Ahers\Downloads\reactnative-beautiful-ui-master (1)\reactnative-beautiful-ui-master\android\app\debug.keystore' not found for signing config 'debug'. error Failed to install the app. Make sure you have the Android development environment set up: https://reactnative.dev/docs/environment-setup. Run CLI with --verbose flag for more details.Error: Command failed: gradlew.bat app:installDebug -PreactNativeDevServerPort=8081Note: C:\Users\Ahers\Downloads\reactnative-beautiful-ui-master (1)\reactnative-beautiful-ui-master\node_modules\react-native-gesture-handler\android\src\main\java\com\swmansion\gesturehandler\react\RNGestureHandlerButtonViewManager.java uses or overrides a deprecated API.

Here's my build.grade code:

// Top-level build file where you can add configuration options common to all sub-projects/modules.buildscript {    ext {        buildToolsVersion = "28.0.3"        minSdkVersion = 16        compileSdkVersion = 28        targetSdkVersion = 28        supportLibVersion = "28.0.0"    }    repositories {        google()        jcenter()    }    dependencies {        classpath("com.android.tools.build:gradle:3.4.1")        // NOTE: Do not place your application dependencies here; they belong        // in the individual module build.gradle files    }}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()    }}

I tried running this command in order to fix it but it didn't work:

keytool -genkey -v -keystore debug.keystore  -storepass android -alias androiddebugkey -keypass android -keyalg RSA -keysize 2048 -validity 10000

I'm honestly not sure what to do so I would appreciate any suggestions.
