I am also facing the exact same problem. found no solution
same error has just occurred for the first time
For me, this issue went away when I fixed another error caused by duplicate library classes. I went to Assets/Plugins/Android, clicked on the culprit (in my case it was the “com.unity3d.ads.unity-ads-4.5.0” plugin and then unchecked Android as a selected platform for the plugin. After this, I was able to build.
