Cannot get app name correctly in android API 30 or higher

I want to get a list of app names installed on android phone. However, when I run my code, I can't get some of the app names correctly as shown below.

D/applicationName: com.android.gallery3d.app.GalleryActivity
D/applicationName: Messaging
D/applicationName: Settings
D/applicationName: Maps
D/applicationName: com.android.documentsui.LauncherActivity
D/applicationName: res/menu/example_menu.xml
D/applicationName: res/color/abc_primary_text_material_light.xml

Also, when the correct app name cannot be obtained, the following error occurs

E/mple.getapplis: Resource 7f100082 is a complex map type.
W/PackageManager: Failure retrieving text 0x7f100082 in package com.android.documentsui
    android.content.res.Resources$NotFoundException: String resource ID #0x7f100082

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:947)

Sometimes I get a list of each app name is correct, but after a few builds, the above situation occurs. And this situation occurs only if my code runs in api 30 and above. My code is below.

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val pm = this.packageManager
        val intent = Intent()
        intent.action = Intent.ACTION_MAIN
        intent.addCategory(Intent.CATEGORY_LAUNCHER)
        val applications = pm.queryIntentActivities(intent, 0)
        for (resolverInfo in applications) {
            val applicationName = resolverInfo.loadLabel(pm).toString()
            Log.d("applicationName", applicationName)
        }

    }
}

I already added following setting in AndroidManifest.xml

<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES"
    tools:ignore="QueryAllPackagesPermission" />

Does anyone know how to fix it?

I removed my app and rebuilt, this problem was solved! I think this is a bug of IDE.

try this

public String getAppLable(Context context) {
PackageManager packageManager = context.getPackageManager();
ApplicationInfo applicationInfo = null;
try {
    applicationInfo = packageManager.getApplicationInfo(context.getApplicationInfo().packageName, 0);
} catch (final NameNotFoundException e) {
}
return (String) (applicationInfo != null ? packageManager.getApplicationLabel(applicationInfo) : "Unknown");

}
