EXC_BAD_ACCESS KERN_INVALID_ADDRESS crash in AsyncBluetoothLogging.logger(for:)

[curioustechizen]

(Disclaimer: I'm using a very old version of the library - 1.12.0, so this should not be a bug. Instead it should have been a Question but I don't see a Discussions section in this library so I'm asking the question here instead).

Recently we introduced a new flow in our app that checks the status of Bluetooth at a certain point in the app. Since then, I see several crashes in production with the following stack trace:

Crashed: com.apple.root.user-initiated-qos.cooperative

I do see this crash in testing but it is difficult to pin-point the exact steps that repro it. It seems to be related to calling waitUntilReady while the Bluetooth is turned off from the Settings app (it does not seem to occur if Bluetooth is turned off from Control Center). The code that I use looks like this where asyncBtCentralManager is an instance of CentralManager from AsyncBluetooth library.

  func getBluetoothStatus() {
      Task {
          try await asyncBtCentralManager.waitUntilReady()
          let btState = asyncBtCentralManager.getCbState()
          // Do something with btState
      }
  }

I don't expect this to be fixed in the library. But do you have any ideas on how I could work around it in my app? Should slapping a @MainActor in on the Task above be enough?
