无法删除附加到其他FragmentManager的Fragment

Question

在我的android项目中：

gradle.properties：

android.useAndroidX=true
android.enableJetifier=true

在build.gradle中：

implementation 'commons-io:commons-io:2.6'
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'org.apache.commons:commons-lang3:3.8.1'
    implementation 'com.google.android.gms:play-services:4.3.23'
    implementation 'com.google.code.gson:gson:2.8.5'
    implementation 'com.nineoldandroids:library:2.4.0'
    implementation 'edu.vt.middleware:vt-password:3.1.2'

我的片段

import androidx.fragment.app.FragmentManager;
com.google.android.gms.maps

public class AgentsFragmentMapTab extends Fragment {
private SupportMapFragment mapFrag;

 @Override
    public void onDestroyView() {
             super.onDestroyView();
        try {
            if (mapFrag != null) {
                FragmentManager fm = thisFragmentActivity.getSupportFragmentManager();
                fm.beginTransaction().remove(mapFrag).commit();
                     thisFragmentActivity = null;
            }
        } catch (IllegalStateException e) {

        }
}

此行中的运行时错误：

fm.beginTransaction().remove(mapFrag).commit();

错误消息：

Cannot remove Fragment attached to a different FragmentManager. Fragment SupportMapFragment{9b891cc (9a1b8486-fe26-4e78-8628-b7647fae31ff) id=0x7f0901d1} is already attached to a FragmentManager.
