I found a version 5.2.2 of the Youtube addon that works perfectly.
After some research, it turns out that previous versions of the addon doesn't work correctly with Kodi Krypton.
I don't understand why all the tutorials I looked they put .apps.googleusercontent.com in the Client ID.
But thank you all for the help and without the advice removing .apps.googleusercontent.com I would still be looking for a solution.
