这个错误发生在应用程序启动时，原因是Android无法获取启动提供程序。这可能是由于某些库版本不兼容或缺失，或者在AndroidManifest.xml中的提供程序声明中出现问题。
首先，您可以尝试清除应用程序缓存并重新启动应用程序，看看是否解决了问题。如果没有，请尝试更新所有库到最新版本，并确保在AndroidManifest.xml中声明的提供程序是正确的，并且与使用的库版本兼容。
如果问题仍然存在，请尝试使用以下代码来查看更详细的错误信息：
try {
// Your code here
} catch (RuntimeException e) {
Log.e("MyApp", "RuntimeException", e);
throw e;
}
这将记录更详细的堆栈跟踪，可能有助于确定问题的根本原因。
