Android Studio 3.3.1，Anko支持0.10.7：在没有预览的情况下出现灰屏

Question

使用此配置，我看不到Anko Preview的任何预览，只有灰色屏幕。救命，我被封锁了！

我使用了太多的Anko Library 0.10。*，但它不起作用，我的预览只有灰色，截止日期不远，我在这个问题上待了一个星期，求助！如果任何人都有一个很好的解决方案。

我删除了 Android Studio 3.3.1 ，并安装了 AS 3.2 （包括 kotlin 1.2.71 ）+“ ext。 gradle文件中的anko_version ＝'0.10.7'。 之后，一切正常。
