LG LED 55UK6200 problem with Youtube app

[IvanRua]

When I try to play a Youtube video in the app, it doesnt play. It stays all black as you can see in the image. It is the only app with problems. Netflix and others work well.
I tried reinstalling the app, reseting the tv to factory settings, updating everything... Nothing worked.
Do you know what is happening?
Thank you

Can you cast Youtube videos from say phone YT app to the TV, do they play that way ?
