packageManager.queryIntentActivities(intent, 0) will return EMPTY list if your app is running on targetSdkVersion 30 to resolved this issue you have to use <queries> in menifest as queryIntentActivities(), are filtered based on the calling app's declaration.

The issue can be related to new package visibility (https://developer.android.com/about/versions/11/privacy/package-visibility). After all updates (at least Android Studio 4.1) try to add in your manifest that shows what action is required in app. In my case problem disappears when adds.

IMAGE_CAPTURE for CAMERA, GET_CONTENT for GALLERY (to get files change mimeType if you want video), PICK for GALLERY (should change mimetype if u want video) CHOOSER for GALLERY (if someone have other image browsers)

You can also check in logcat what queries you have to add (should contains "BLOCKED" or "no permission". Error is because ImagePickerModule when you don't have permission in Intent with resolveActivity returns null (you can comment it to check better errors in startActivityForResult)

Add <query> in AndroidMenifest.xml

<manifest>
.....
.....
<queries>
    <!-- Browser -->
    <intent>
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="http" />
    </intent>
    <!-- Camera -->
    <intent>
        <action android:name="android.media.action.IMAGE_CAPTURE" />
    </intent>
    <!-- Gallery -->
    <intent>
        <action android:name="android.intent.action.GET_CONTENT" />
        <data android:mimeType="image/*" />
    </intent>
    <intent>
        <action android:name="android.intent.action.PICK" />
        <data android:mimeType="image/*" />
    </intent>
    <intent>
        <action android:name="android.intent.action.CHOOSER" />
     </intent>

     <!--For external application-->
     <package android:name="com.whatsapp" />
</queries>
.....
.....
</manifest>
