[Bug] Failed to read user data for app (__FIRAPP_DEFAULT).

### Description

Hey there, I upgraded my Meta Quest Unity Project from using Firebase 10.5 to 12.3 and 12.4 recently and now Auth totally hangs in the
`SignInWithEmailAndPasswordAsync` call.

This just happens in my Windows Editor, not in Android Build. And surprisingly this does not happens (same repo and everything) in my Mac Editor (connected to the same network).

I have tried with #1048, and also the VPN solution suggested in #1098.
I have also tried nuking the Library and Temp folders.

I have been using this project for a few years now, and never had trouble.

### Reproducing the issue

Open Unity in Windows.
Check Firebase Dependencies.
Initialize Firebase.

The console will output:
```
Failed to read user data for app (__FIRAPP_DEFAULT). This could happen if the current user doesn't have access to the keystore, the keystore has been corrupted or the app intentionally deleted the stored data.
```

Call SignInWithEmailAndPasswordAsync.
It will never finish that async call.

After stopping Unity I get:
```
SignInWithEmailAndPasswordAsync encountered an error: System.AggregateException: One or more errors occurred. (An internal error has occurred.) ---> Firebase.FirebaseException: An internal error has occurred.
