Я получаю один сбой при сбое в java.util.ArrayList com.android.server.am.ActivityStackSupervisor $ ActivityDisplay.mStacks .но я не могу найти, где это крушение.

HomeActivity: com.lendlease.plus.activity.HomeActivity.onBackPressed

заголовок показывает ошибку в onBackPressed, но я не использовал ни одного массива в этих методах.также я не могу воспроизвести это.

onBackPressed (): 

 @Override
    public void onBackPressed() {
        if (prefManager.getString(PARAMS.KEY_IS_GUEST, "").equals("1")) {
            if (mBinding.bottomNavigation.getSelectedItemId() != R.id.tabExplore) {
                Constants.TAB_SELECTED = Constants.TAB_EXPLORE;
                mBinding.bottomNavigation.setSelectedItemId(R.id.tabExplore);
            } else {
                Intent intent = new Intent(Intent.ACTION_MAIN);
                intent.addCategory(Intent.CATEGORY_HOME);
                intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivity(intent);
                finish();
            }
        } else {
            if (mBinding.bottomNavigation.getSelectedItemId() != R.id.tabToday) {
                Constants.TAB_SELECTED = Constants.TAB_TODAY;
                mBinding.bottomNavigation.setSelectedItemId(R.id.tabToday);
            } else {
                Intent intent = new Intent(Intent.ACTION_MAIN);
                intent.addCategory(Intent.CATEGORY_HOME);
                intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivity(intent);
                finish();
            }
        }
    }
