Problem with Google SigIn when re-logging into Firebase

I'm having a little problem logging into FirebaseUsing Google SigIn. The issue is that I am managing to log in with this method, but when some problem occurs after selecting some Account (figure below) I can no longer choose another account to try to log in again, it insists on the same account, but for not authenticating it becomes unfeasible to proceed.

The idea I want is that when generating the error, it allows me to choose another account, or let him show me this popup again.

I don't want to put another login method for now.

Follows the code I'm using:
