I basically copy paste the code he uses in his tutorial
I am encountering a NullPointerException in the Meta Voice SDK while attempting to activate AppVoiceExperience in my Unity project. The error occurs when the SDK tries to access Android's Looper.mQueue during initialization. I am on Mac.
I am developing for the Meat Quest 3. I have the Latest version of the Meta Voice SDK installed (v71) as well as the latest version of the Meta Core SDK. I do NOT have the Meta All in One SDK installed. I've set up all the Wit voice configuration files as well.
appVoiceExperience.Activate();
This code is causing the error. When I run it in game mode. I dont get an error
Here is the exact error:

This happens regardless of whether I call Activate() in the Awake, Start, or through a delayed coroutine. The same error persists in all cases.
Here are some of my key observations:
Im actually also getting the exception before my script is even called.
Awake in VoiceManager is successfully called, but Start encounters the NullPointerException.
Even delaying the Activate() call with a coroutine or button click does not resolve the issue.
The required permissions (RECORD_AUDIO, INTERNET, FOREGROUND_SERVICE) are all declared in the AndroidManifest.xml, and the app has been granted these permissions on the device.
