Error running ADS on android phone

Hello, my name is Alexander. I'm developing a videogame using Unity Ads and IAP.
When I tested my game only with IAP, works fantastic (Connected and disconnected), but now I integrated Ads and only runs on the editor, on my android phone only crashes.

I followed instruction on Integration guide, for initialization, and use, but after initialization, my game crashes.

I attached my manager script and the logcat, this is inited on splash screen. (I commented the ads initialization for other mechanics testing).

I don't know what I'm doing wrong.
