facebook audience-network-sdk -> java.lang.NoSuchMethodError onAdEventManagerCreated when updating to recent versions

I'm using 6.5.1 with no problems:

implementation 'com.facebook.android:audience-network-sdk:6.5.1'

            bannerListener = new AdListener() {
                @Override public void onError(Ad ad, AdError adError) {}
                @Override public void onAdLoaded(Ad ad) {}
                @Override public void onAdClicked(Ad ad) {}
                @Override public void onLoggingImpression(Ad ad) {}
            };
            loading = true;
            banner = new AdView(context, id, AdSize.BANNER_HEIGHT_50);
            banner.loadAd(banner.buildLoadAdConfig().withAdListener(bannerListener).build());

But if I update the sdk to 6.11.0 or even 6.6.0, i'm getting this exception:

java.lang.NoSuchMethodError: No interface method onAdEventManagerCreated(Landroid/content/Context;)V in class Lcom/facebook/ads/internal/api/InitApi; or its super classes (declaration of 'com.facebook.ads.internal.api.InitApi' appears in /data/data/com.myapp.core/code_cache/.overlay/base.apk/classes.dex)

The error line is banner = new AdView(context, id, AdSize.BANNER_HEIGHT_50);

Does anyone have any idea about what is happening?

I'm building with api 31:

android {
    compileSdkVersion 31
    buildToolsVersion '31.0.0'

    defaultConfig {
        minSdkVersion 21
        targetSdkVersion 31
    }

Well, I simply deleted Android Studio cache and restarted it... now it works...

Seems that some bug on it was producing the issue. Don't sure what, but a restart with cache cleaning solved it.
