我之前有Google Play服务，但从统一2018.1升级到2018.2后，它似乎停止工作了。 （我不确定是不是升级引起的）
在统一日志中，我可以看到：
Starting Auth with token client.
!!![Play Games Plugin DLL]07/17/18 15:49:08 +02:00 WARNING: Creating new PlayGamesPlatform
Building GPG services, implicitly attempts silent auth
然后应用崩溃
在发布前报告中，我可以看到它在应用启动时（从logcat）崩溃：

从预启动开始，它在Pixel 2手机上也没有错误。（也许是因为它是唯一运行android P预览的手机）
我尝试过：
使用sdk重新安装android studio
从github重新导入Google Play游戏以实现统一
更改Google Play解析器设置以使用较早的.aars（已在10.6.2 | 10.0.1 | 10.0.4中进行测试）
对AndroidMainfest.xml进行了更改，如其他线程所示，但是这些解决方案大多数由于在构建中失败，因为它们覆盖了已经存在的条目（与我尝试添加的条目相同）
对于如何使它再次工作，我没有其他想法。因此，任何建议都将受到赞赏。
