Application expected to run in background on interval crashes without LOGCAT after 500-1000 iterations

My application is expected to be run once by the user and the background process will run indefinitely as the app runs. The background process is supposed to run a handler (I use badoo WeakHandler) on 5s interval.
However, after 500 - 1000 iterations of the interval, the application would terminate itself without any notification on the logcat (I will provide the screenshot later). I set my logcat to Verbose and No Filter.

How can I make sure that the application can run reliably without crashing?

build.gradle(:app)

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.2"
    defaultConfig {
        applicationId "com.example"
        minSdkVersion 21
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation 'com.badoo.mobile:android-weak-handler:1.0'
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.0'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
}

My application only has one activity, which is MainActivity.java.
Here is my Runnable

    private Runnable captureInterval = new Runnable() {
        @RequiresApi(api = Build.VERSION_CODES.O)
        @Override
        public void run() {
            android.os.Process.setThreadPriority(android.os.Process.THREAD_PRIORITY_BACKGROUND);
            if (mMediaRecorder != null) {
                File f = new File(videoPath);
                try {
                    mMediaRecorder.stop();
                } catch (RuntimeException e) {
                    f.delete();
                    e.printStackTrace();
                } finally {
                    mMediaRecorder.release();
                    mMediaRecorder = null;
                }
            }
            if (mVirtualDisplay != null) {
                mVirtualDisplay.release();
                mVirtualDisplay = null;
            }
            if (!mKeyguardManager.isKeyguardLocked()) {
                initRecorder();
                shareScreen();
            }
            mHandler.postDelayed(this, 5000);
        }
    };
