ANR is caused when querying installed application names from app

Question

For security purpose, we are just querying over the installed apps on the android device to make sure malicious apps are not present.

Following is the code(pseudo) I am using to do that:

suspend fun getInstalledApplicationAsync(...) {
        val appList : MutableList<ApplicationsItemRequest> = mutableListOf()
        val apps = packageManager?.getInstalledApplications(0)
        val installedApps = ArrayList<ApplicationInfo>()
        apps?.forEachIndexed{ index, element ->
        // line as per logs causing ANR
        val label = packageManager.getApplicationLabel(element)
       }
}
