Okay, so I'm having some very odd behaviour that doesn't make much sense in my app.
My app uses BLE and I have a static class which I initialize on app launch, this typically works with no issue.
Today I made a single change in my app which was to update this:
implementation 'com.google.firebase:firebase-core:17.2.1'
implementation 'com.google.firebase:firebase-messaging:20.0.0'
To this:
implementation 'com.google.firebase:firebase-core:17.2.2'
implementation 'com.google.firebase:firebase-messaging:20.1.0'
And after making this minor version update to firebase core, my app now immediately crashes on launch with the following error:

Note: My app does not use dagger at all, though the RxBLE library might...
If I revert the firebase update the app builds and runs with no issue, so for now I'll just stick to using firebase-messaging:20.0.0 and firebase-core:17.2.1, but does anyone have any clue why this might be happening?
This is the only line of code required to make the crash happen:
RxBleClient.create(applicationContext)
Here is a test repo that you can reproduce the crash in: https://github.com/Doophie/TestAppCrash
Note that there are 2 commits, in the first commit the app has updated firebase and crashes, the second commit it does not crash and uses the older firebase version.
