Android app opens info screen instead of main Activity on launch

I am encountering an issue midway through developing an app. When I disconnect my app from Android Studio and my PC after coding, launching my app on my phone leads to the app info screen (force stop, clear memory) instead of my main activity. When I relaunch my activity by connecting with Android Studio, it works fine. I have not encountered this issue when working on other apps.

The code from my app manifest is included below:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.meanings_downloader">

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"            />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<application
    android:requestLegacyExternalStorage="true"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

    <activity android:name=".Music_Activity"></activity>
    <activity
        android:name=".SettingsActivity"
        android:label="@string/title_activity_settings" />
    <activity android:name=".settings" />
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
      <action android:name="android.intent.action.SEND" />
            <data android:mimeType="*/*"/>
            <category android:name="android.intent.category.DEFAULT"/>


            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <service android:name=".Music" >
        <intent-filter>
            <action android:name="android.media.browse.MediaBrowserServic"/>
        </intent-filter>
    </service>
</application>

Have I encountered an issue, or am I doing something wrong?

You have encountered an issue. The issue is likely caused by the android:exported attribute missing in your MainActivity declaration. Add android:exported="true" to the <activity> tag for your MainActivity in the app manifest.
