classNotFoundException：android.view.onbackinvokedCallback，构成1.2.0-alpha07
由于更新到androidx.com pose 1.2.0-alpha06我看不到任何预览。我在任何地方都没有发现类似的问题。预览渲染器与以下消息

相似问题没有任何人回答。 应用指定的解决方法在这里 尽管情况似乎与我的情况相似，但错误与我的不同，我想这就是原因。 我看到了一个设置与撰写版本相同的作曲版本所需的问题，这无济于事。我的Activity-KTX版本是1.6.0-Alpha01。
我正在使用 Android Studio Bumblebee | 2021.1.1补丁3
Since updating to androidx.compose 1.2.0-alpha06 I'm unable to see any previews. I haven't found similar issues anywhere. Preview renderer crashes with the following message

Similar issue has not been answered by anyone.
Applying the workaround specified here did not work, although the case seems similar to mine, the error differs from mine, I guess that's the reason.
I saw an issue that required to set the same compose-activity version as compose version, it did not help. My activity-ktx version is 1.6.0-alpha01.
