What would cause this exception? I’ve narrowed it down to an ExoPlayer view, but the problem is I don’t know why it’s doing it

if it is possible for you to share the sources of the project where it is reproducible and file a bug with it we can try to fix it

I can try to do that. I’ve narrowed it down to setting the exoplayer’s 
player.playwhenready = true
If I delay that by a few 100 milliseconds, it works without issues
