I think you should check:

GoogleSignIn.hasPermissions(account, Games.SCOPE_GAMES_LITE).

And if there is no permissions in that account you should use

GoogleSignIn.getClient(this, gso).silentSignIn or GoogleSignIn.getClient(this, gso).getSignInIntent() 

with startActivityForResult to receive account with GAMES_LITE scope.

GoogleSignIn.hasPermissions also returns false for null account which could be also result of the getLastSignedInAccount.

Example:

GoogleSignInAccount account = GoogleSignIn.getLastSignedInAccount(this);

if (GoogleSignIn.hasPermissions(account, Games.SCOPE_GAMES_LITE)) {
    onSignIn(account);
} else {
    signInClient
      .silentSignIn()
      .addOnCompleteListener(
          this,
          task -> {
            if (task.isSuccessful()) {
              onSignIn(task.getResult());
            } else {
              resetSignedIn();
            }
          });
}
