3D Model viewer not loading

I am using a flutter library called Model Viewer ModelViewer

That's a very nice plugin which works like charm on my dev version of that app. I am using it like this:

  ModelViewer(            backgroundColor: Colors.black,            src: 'assets/skull.glb',            alt: "A 3D model of a skull",            cameraControls: true,          ),  

And the .glb model is in the assets folder. My flutter is latest stable version as well as the version of this plugin.

The strange thing it that when I build the app bundle and publish the app on google play, when I navigate to the page with the model viewer the widget never loads.

I can only see a white screen.

Both the dev version and the release are tested on a physical device with android 10.

I am not sure how to debug this but would be happy for any suggestions. Can't find any solution from the original repo.

UPDATE

That's the error from the logcat:

Thank you.
