Question Gradle build fails after installing unity ads package

Hi everyone. I've got an android project going on and it all goes smoothly until i try to implement ads. As soon as i turn on the unity ads and install the ads package, my game doesn't build anymore and gives me this Gradle build failed error. I've really tried anything so everything helps. Thank you.

Console:
