[Bug] Error caught by debugger on each recompile when in play mode

[tomkail]

Description

When my debugger (Rider) is connected, each time Unity recompiles due to code being edited while Unity is running, the follow exception is thrown. This makes it very annoying to leave my debugger attached.

System.ArgumentNullException: "_p_firebasefirestorecsharp__TransactionManager" has been disposed at Firebase.Firestore.TransactionManagerProxy.CppDispose () [0x00016] in /home/runner/work/firebase-unity-sdk/firebase-unity-sdk/linux_unity/firestore/swig/Firebase.Firestore_fixed.cs:3644 at Firebase.Firestore.TransactionManager.Dispose () [0x0000d] in /home/runner/work/firebase-unity-sdk/firebase-unity-sdk/firestore/src/TransactionManager.cs:63 at Firebase.Firestore.FirebaseFirestore.Dispose () [0x0004c] in /home/runner/work/firebase-unity-sdk/firebase-unity-sdk/firestore/src/FirebaseFirestore.cs:96 at Firebase.Firestore.FirebaseFirestore.Finalize () [0x00002] in /home/runner/work/firebase-unity-sdk/firebase-unity-sdk/firestore/src/FirebaseFirestore.cs:76

If using CocoaPods for Apple platforms, the project's Podfile.lock

Expand Podfile.lock snippet

```yml 👀 Replace this line with the contents of your Podfile.lock! ```

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

Hey @tomkail , thanks for reporting. Does the issue occur consistently? Would you be able to give me a full log?

It looks as though there's a race condition and the code is trying to dispose of something that's already been disposed.

[tomkail]

Yeah, it's been happening fairly consistently since I've been using the package, over a year. I wrote in via the website (since that's where the downloads for Unity are hosted) but never heard back; I only realised this github existed recently. How can I get the full log?

[ehsannas]

Set FirebaseFirestore.LogLevel = LogLevel.Debug as early as possible in your application. Reproduce the crash. Depending on your environment you should be able to find the crash log.
