I tried google lot, reinstalled different versions of unity, reinstalled java, tried different versions of firebase sdk, but still bug, error does not occur often so i have to try again 20 times The error can reappear. I do not know what to do anymore :(

I'm having the exact same error on unity sdk 5.2.1, it seems to be random but it completely freezes the app.

If I also miss the error that is happening

Hi Gustavo,

We are investigating this. Are you also using Auth and Database with the Play Games Unity plugin?

Jon

[Gustavo Bogarín]

I'm only using the Firebase SDK.

// We use this to login.

FirebaseAuth.DefaultInstance.SignInWithCustomTokenAsync(token).ContinueWith((loginTask) =>...

// We use this for logout, but the crash occurs even if this code is not executed.
FirebaseAuth.DefaultInstance.SignOut();

But another member of the team is in fact using the Play Games Unity plugin, and this is how the authentication is done in his code.

PlayGamesPlatform.Instance.GetServerAuthCode();

That part of the code is not yet on the master branch and the crash stopped after I removed the first two calls, if that info helps you, thank you.
