IUnityBannerListener class not found

Hi,
I have this error on the android device.
Unity 2019.3.14f1 Unity ads 3.4.5

2020-05-29 14:33:43.689 4392-4445/? E/Unity: java.lang.ClassNotFoundException: com.unity3d.services.banners.IUnityBannerListener
UnityEngine.Logger:Log(LogType, Object)
UnityEngine.Advertisements.Advertisement:CreatePlatform()
UnityEngine.Advertisements.Advertisement:.cctor()

I even don't use banners, I have this error on initialization.
