Error After Changing Package Name

[Gustavo_Niederauer]

I have an app with a current package name (com.br.fretespaiva.guslab) and is working fine.
But now I need to replace this package name (com.br.pistadupla.guslab) because I will publish to Play Store.
When I change it and try to export I am not able to save as aab. or .apk
I receive “Something went wrong”
If I set back to the old package name(com.br.fretespaiva.guslab) back it completes the Export with no problem.

What can be the error?

Have you used firebase auth in your app?

Fantastic!!!
the error was that. was about firebase.
I forgot about it
So, I went to firebase and create a new app and download a new google-services.json file

Thank you
