Importing Facebook SDK on project makes the build crash on Android

Question

I have a simple 2D game that I want to use Facebook SDK to allow users to share information on social media. I tried importing the new version of Facebook SDK in the official website, set up the App Id and when I build my project, even if I'm not using anything related to Facebook on my project, the app simply crashes without even opening the Unity Splash Screen.

I tried installing older versions, changing the Android Manifest file and lots of other things but nothing seems to help, does anyone know what may be causing it?

Extra info:

Unity Version: 2019.1.14f1 (in External Tools for Android I'm using JDK, Android SDK, Android NDK, etc installed with Unity)
Tested Facebook SDK versions: 7.17.2, 7.16.1, 7.15.1

Edit: I tried other things suggested in different forums as changing my AndroidManifest.xml file, deleting the FacebookSDK/Plugins/Android/libs directory, different settings in the facebook's developer page but nothing works, no one has any idea of what is causing this?

Just solved my problem so I'll explain it here in case someone else has the same difficulties.

I was assuming I did something wrong with the Facebook configuration in my Project, but I noticed that even though Facebook said everything was ok, Force Resolving the Play Services showed an error saying Gradle failed to fetch dependencies. that I did not notice before... Which was caused by my project name having an '!' character, which I assume the GooglePlayServicesResolver can't process correctly.

Changing the project name and force resolving the play services (right-click anywhere in you project folder and then go to Play Services Resolver->Android Resolver-> Force Resolve)

Something like this? (sorry, not familiar with android logs, I used adb logcat and searched the exception)

java.lang.RuntimeException: Unable to get provider com.facebook.FacebookContentProvider: java.lang.ClassNotFoundException: Didn't find class "com.facebook.FacebookContentProvider" on path: ...

export project on unity build. there is a check box to export, then you can debug on android studio better.

I figured, I tried openning it here as well and nothing... Unity's not showing it properly, but if you just use ctrl + s you should be able to download it ^^
