Steps to reproduce:

/PATH/Assets/GoogleMobileAds/Editor/ManifestProcessor.cs

Before
string manifestPath = Path.Combine(Application.dataPath, Plugins/Android/GoogleMobileAdsPlugin.androidlib/AndroidManifest.xml");

After
string manifestPath = Path.Combine(Application.dataPath, Plugins/Android/GoogleMobileAdsPlugin/AndroidManifest.xml");

This happened because you upgraded from an old version of admob.
From the version 5.2.0 the folder structure was changed.

Plugins/Android/GoogleMobileAdsPlugin was changed to Plugins/Android/GoogleMobileAdsPlugin.androidlib
And the same with the manifest processor

This is not a bug. Is intended to make it work with unity newer versions like 2020.1

If you make a fresh install of the plugin it will work fine.

Please make a fresh install of the plugin
