[Bug] Persistent connection error thrown when using Unity 2022 on Mac about firebase-unity-sdk

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hey @lmt385, thanks for reaching out. I'm trying to test your scenario using our quickstart repo but it seems to work just fine. I'm testing with version Firebase Realtime Database 11.9.0 and Unity Editor 2022.3.24f1. That said, could you answer the following:

1. You mentioned in [3] that "Error is triggered referencing persistent_connection.cc". Are you saying after adding ValueChanged callback, the error is already triggered?
2. Can you provide a MCVE so that we can check if there's a difference in setup that's causing this issue"

Thanks in advance!

Hello,
The error triggers upon the callback being registered, yes.

I'll see what I can do in terms of providing a MCVE.

Edit: While digging deeper, it doesn't seem to be triggering upon the listeners being registered, but at a later point related to the initial callbacks when calling GetValueAsync.

The general flow is:

1. 3 OnValueChanged callbacks assigned, followed by 7 more once those are finished
2. The ValueChanged callbacks in turn call a method that uses GetValueAsync for a child reference, if the value returned by the callback meets a condition
   a. So, it goes: ValueChanged Callback associated with reference.Child("attribute") -> Callback checks if condition is met -> Method that calls await reference.Child("setting").GetValueAsync()
3. On the Mac Editor, GetValueAsync is triggering the persistent_connection.cc error if present in this flow. When commented out, the code executes without issue. GetValueAsync does not cause an error if it is not associated with the callback.
