从 Firebase Crashlytics 收到的崩溃报告数量。我认为这与 firebase-perf 有关。

Fatal Exception: java.lang.NoClassDefFoundError: com.google.android.gms.internal.firebase-perf.zzw
   at com.google.firebase.perf.metrics.Trace.start(Unknown Source:44)
   at com.google.android.gms.internal.firebase-perf.zze.onActivityStarted(Unknown Source:48)
   at android.app.Application.dispatchActivityStarted(Application.java:205)
   at android.app.Activity.onStart(Activity.java:1150)

已在使用最新版本的 Firebase 和 Google Play 服务。

它不会在 Firebase 测试实验室中的设备上崩溃。但是大约 1% 的用户面临这个问题。

是否与缺少 GMS Core 有关?如果是这样,如何正确处理它,而不导致这些设备崩溃?

Firebase 支持刚刚确认我这是一个错误。他们现在正在研究这个(尽管他们还不能复制它)。所以我们应该期望在未来的 Firebase 版本中解决这个问题。
