Android 数据存储 IOException 无法重命名为

我正在尝试在我的项目中实现 Jetpack Datastore。我当时用的是apha-01版本和代码工作正常。然后我在Gradle文件中看到有新版本所以我将其更新为alpha-03.

启动我的应用程序后，我遇到了另一个问题。我发现Proto库中没有找到alpha-03版本所以我回滚到版本alpha-01。另外，我尝试过alpha-02。从那时起我遇到了以下错误：

 Process: com.montymobile.sands, PID: 19928
    java.io.IOException: /data/user/0/com.montymobile.sands/files/datastore/sns_preferences.preferences_pb.tmp could not be renamed to /data/user/0/com.montymobile.sands/files/datastore/sns_preferences.preferences_pb

        at kotlinx.coroutines.scheduling.CoroutineScheduler$Worker.run(CoroutineScheduler.kt:665)

我注意到发生这种情况是因为我依次保存了两个不同的密钥，每个密钥都在一个协程中。当我评论第二个操作时，它起作用了。 谁能解释为什么会发生这种情况？以及如何保存我想要的尽可能多的值？

任何帮助，将不胜感激。
