firebase-ios-sdk: Crash when Launch APP

• Xcode version: 10.3

• Fabric (1.10.2)
• Firebase/Analytics (6.7.0):
• Firebase/Core(6.7.0):
• Firebase/Performance(6.7.0):

When the APP is in the background for a long time, then cut back the APP from the background, Caton crashes after a few seconds on the launch page.

Small probability time

Steps to reproduce:

What happened? How can we make the problem occur? This could be a description, log/console output, etc.
