I’m running into a build inconsistency between unity versions 2022.3.19f1 and 2022.3.25f1. To preface, 2022.3.19 had a bug with the TMP input field where, on Android, the touchscreen keyboard wouldn’t always appear correctly. I was told it was fixed in 2022.3.25. After confirming it, I updated the project to that version.
However, when I build on the new version, I would get an null exception that I don’t get on the older version, or in both version of the editor. This only happens when I build it on Android, afaict. The app works perfectly fine in both versions of the editor, and works fine when built from the older version. The Null exception is caused by the Sign in functions for Firebase.Auth (SignInAnonymouslyAsync() and SignInWithEmailAndPasswordAsync()) inside a script called FirestoreAuthenticator.
The Bug I get on Android:
AndroidPlayer "Samsung_SM G973U@ADB:RF8MB27GHGA:0" NullReferenceException: Object reference not set to an instance of an object.

Both FirestoreController and FirestoreAuthenticator are placed on the same game object that is always enabled.
ConnectivityCheck is a static script shared between multiple scenes.
The way that the script works is that one Awake(), FirestoreController initiates Firebase references. FirebaseAuthenticator that sets itself as the static reference for “auth” within ConnectivityCheck. FInally Connectivity Checks checks if there is a internet connection before signing in with the appropriate sign-in method. In app, it’s always SignInAnon(), called by CheckSignIn().
The Null exception is in the SignIAnonymousAsync() (I tested it with SignInWithEmailAndPasswordAsync() as well, same bug).
I thought maybe the new version didn’t like the static ConnectivityCheck script, so I made a version that was non-static and placed it onto the same game object, where the references were serialized and assigned in the inspector - same bug.
From what I can tell, 2022.3.25f1 doesn’t seem to like how my Firebase is Initialized. Is there changes in the new version I need to be aware of? Is the version of Firebase not supported?
To summarize, the app works perfectly fine in BOTH version of the editor and when built on the 2022.3.19f1. No code was changed between the two build versions initially. And none of the code changes I made in an attempt to fix the issue fixes the bug. It’s the excact bug:
