My application is not launched in Android Emulator - android-studio

Question

I am new to the development of mobile applications with Android.
The Kotlin application once built, does not appear in the android-studio emulator (Pixel XL API 30: Android 11.0 (Google API))
ADB is unable to debug the application:
$ adb shell am start -n "paris.ksainthi.soundpark/paris.ksainthi.soundpark.MainActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Timed out waiting for process (paris.ksainthi.soundpark) to appear on Pixel_XL_API_30 [emulator-5554].
The application is present in the list of applications in the configuration. But it is not on the home, nor launched.
Here is my build.gradle file:
plugins {
id 'com.android.application'
id 'kotlin-android'
}
android {
compileSdkVersion 31
buildToolsVersion '30.0.2'
defaultConfig {
applicationId "paris.ksainthi.soundpark"
minSdkVersion 16
targetSdkVersion 30
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = '1.8'
}
}
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
implementation 'androidx.core:core-ktx:1.6.0'
implementation 'androidx.appcompat:appcompat:1.3.1'
implementation 'com.google.android.material:material:1.4.0'

testImplementation 'junit:junit:4.+'

androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
implementation 'com.google.android.material:material:1.5.0-alpha02'
}
Here is the configuration of my application:
Deploy: Default APK
Launch: Specified Activity, paris.ksainthi.soundpark.MainActivity
