Hope this is in the right forum. Building for Android hangs at "Build Player" in the "Building Player" dialog on 2021.3.17f1 that I just installed. It builds fine on the previous 2021.3.16f1. No idea where to look for clues, as Unity is frozen when it happens. Going back to 2021.3.16f1... Update: It builds without the GoogleMobileAds-v7.4.0.unitypackage and GoogleMobileAds-v7.3.1.unitypackage I didn't try previous versions, though. Update 2: It won't build with GoogleMobileAds-v6.1.2.unitypackage either.
