title: Cannot access 'setContent': it is internal in 'androidx.compose.ui.platform'
body: <p>I'm using</p>
  <ul>
  <li>Android Studio 4.3 (Artix Fox | 2020.3.1 Canary 5),</li>
  <li>compose_version = '1.0.0-beta01'</li>
  <li>Kotlin version 1.4.30</li>
  </ul>
  <p>When I open Empty Compose Activity and compile, I got the below error</p>
  <pre><code>e: MainActivity.kt: (9, 37): Cannot access 'setContent': it is internal in 'androidx.compose.ui.platform'
  </code></pre>
  <p>It's so strange as it is a template-generated project, and should work.
  Any workaround it?</p>
