Crash - Sending non-protected broadcast

I've searched this log but everything I've seen just says it's a warning. For some background, this does NOT crash on Oreo, but it DOES crash on Pie. I have no idea what broadcast could be causing it.

I've put breakpoints at every place I call "sendBroadcast" and can confirm that the crash happens before any broadcast is sent from the app.

if you require any code from any class, let me know and I'll put it up immediately

Any idea why this would be crashing on Pie?
