I was able to solve the problem. I recommend that if you are trying to do this on android, watch this video and see the exception you are getting: https://www.youtube.com/watch?v=55rkbsjhA3U
If the error is the same as mine:
NotSupportedException: Encoding 1252 data could not be found. Make sure you have correct international codeset assembly installed and enabled.
They should go to:
Unity\Hub\Editor(UnityVersion)\Editor\Data\MonoBleedingEdge\lib\mono\unityjit-win32
Once there, they must copy the files "I18N.dll" and "I18N.West.dll" and copy them inside the Assets folder, inside your application project, done this, the problem should be solved.
Luck!
