My app is getting a lot IllegalStateException on first launch for some reason, any idea why?

Can you please share detailed logs as this stack trace seems incomplete.

I am also seeing this in my crash logs in the Google console.

Unfortunately, @ened that does seem to be all the info from the stacktrace that is given in the console. It does say that it was on a Motorola Moto Z (2) Play (albus), Android 8.0
