这个错误信息表明在使用 Firebase 的 FCM（Firebase Cloud Messaging）推送时出现了问题。具体错误是 "Unknown error while making a remote service call: Unexpected error refreshing access token"。

根据错误信息的堆栈跟踪，可以看到导致错误的原因是 "java.lang.NoSuchMethodError: com.google.common.io.ByteStreams.exhaust(Ljava/io/InputStream;)J"。这个错误通常是由于不兼容的库版本导致的。

解决这个问题的步骤如下：

确保你的项目中使用的 Firebase 相关库的版本是兼容的。可以尝试更新 Firebase 相关库的版本，确保它们之间的兼容性。可以查看 Firebase 文档或官方网站获取最新的库版本信息。

检查你的项目中是否存在冲突的库。使用不同版本的库可能会导致冲突。可以通过 Gradle 或其他依赖管理工具查看项目的依赖关系，并尝试解决任何库版本冲突。

如果你的项目中使用了 Guava 库（com.google.guava），请确保 Guava 库的版本与 Firebase 相关库的版本兼容。Guava 库是 Google 提供的一个 Java 实用工具库，与 Firebase 一起使用时，版本兼容性很重要。

清理和重新构建项目。有时构建过程中产生的临时文件可能会导致问题。尝试清理和重新构建项目，以确保所有文件和依赖项都是最新的。
