title: Why is Android Studio failing to build, with an AAPT2 error on images?
body: <p>After a recent update, Android Studio fails to build an unmodified project with errors along these lines:</p>
  <pre><code>&gt; A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
  
    &gt; AAPT2 aapt2-4.1.1-6503028-linux Daemon #0: Unexpected error during compile '/path/to/app/src/main/res/mipmap-xxxhdpi/ic_launcher_round.png', attempting to stop daemon.
      This should not happen under normal circumstances, please file an issue if it does.
  </code></pre>
  <p>Notice that it's failing on an image supplied by Android Studio itself!</p>
  <p>What can I do to fix it?</p>
