Bug Firebase & FB SDKs Functionalities not working on the device (Only when built, in editor works fine)

I added the Firebase and Facebook SDK's in my unity project and something weird happened.

My code works perfectly in the Unity Editor (Email/Password and Facebook Login) with no errors whatsoever. BUT, when I build it into iOS and try it out on my code, nothing regarding the SDK works, not even the button that makes the login (It should activate a message that says that I have to fill out the email field, etc..). Even if I fill out the information it doesn't do anything.
The facebook button does trigger the login process, but when it comes to the end and starts to return from the facebook app to mine, it just returns to the login screen as if nothing had happened (It should go to the main screen instead).

As I said in the beginning, everything IS WORKING PERFECTLY in the editor, so I'm guessing It's something not very complex but specific that I don't have to knowledge solve on my own, given that I have dedicated all day on this matter.

Would really appreciate some help and please don't hesitate to ask for information that will help to accelerate this process.

Here are the other posts I made (don't know if I modified something I shouldn't:

Here are some of the errors from the Xcode:
