Exception when opening sceneview fragment, after the activity is already running and has shown other things

Intitial Question:

So I have been in the process of transitioning my AR Project from sceneform to sceneview and I ran into an error. Since I am not sure if that is not yet supported or me doing something wrong, I figured I'd ask here first.

So my app has one MainActivity and a few fragments, but when I start my app it doesn't go straight to AR, but it starts a normal screen first, from where I navigate to the ArFragment later.

When I now am trying to run my app with code similar to your samples, I am getting the error that Camera permission result must be registered before Activity resume

So now I am wondering, with sceneview automatically handling those permissions, is it implemented that the ArFragment needs to be displayed as the first fragment in the app, or am I missing something?

This is the stacktrace: https://pastebin.com/FsMHgBpZ

Yes I did get rid of all of the ArFragment code and yes I am navigating to the Fragment that has the SceneView, after the mainactivity is already running and doing other things. Is that not intended to be possible and do I need to create another Activity for my AR stuff?

@ThomasGorisse I made a small sample project, that has 2 fragments and navigates between the 2 like I do and has the same exception:
