github 주소고 임시방편으로 MainActivity에 아래와같은 코드를 작성해서 해결하긴했습니다. 그렇지만 근본적인 문제가 뭔지 모르겠고, Device UI Shortcut 항목에서 폰트크기를 늘리는 등 ui를 변경하면 에뮬레이터에도 나타나긴합니다. 감사합니다

if (savedInstanceState == null) {  // ✅ 앱이 처음 실행될 때만 Fragment 추가
    supportFragmentManager.beginTransaction()
        .replace(R.id.fragmentContainerView, HomeFragment())
        .commit()
}

activity_main.xml을 아래와 같이 변경해보시겠어요?
