firebase-ios-sdk: Crashed: com.google.fira.worker EXC_BAD_ACCESS KERN_INVALID_ADDRESS

Step 0: Are you in the right place?

• For issues or feature requests related to the code in this repository file a Github issue.
  • If this is a feature request please use the Feature Request template.
• For general technical questions, post a question on StackOverflow with the firebase tag.
• For general (non-iOS) Firebase discussion, use the firebase-talk google group.
• For backend issues, console issues, and other non-SDK help that does not fall under one of the above categories, reach out to Firebase Support.
• Once you’ve read this section and determined that your issue is appropriate for this repository, please delete this section.

[REQUIRED] Step 1: Describe your environment

• Xcode version: 11.5
• Firebase SDK version: 6.30.0
• Firebase Component: Core (6.30.0), Analytics (6.30.0), Crashlytics (6.30.0), Messaging (6.30.0, 4.6.1), Performance (6.30.0), ABTesting (4.2.0), Installations (1.6.0), InstanceID (4.5.1), CoreDiagnostics (1.5.0)
• Component version: please check above
• Installation method: CocoaPods

[REQUIRED] Step 2: Describe the problem

When a 3rd party SDK for monitoring was enabled, crashes happened at Firebase. The crash rate is not so high, so it is difficult to reproduce it. Can you help sort it out, since both tools are needed for us?

Steps to reproduce:

I have not been able to reproduce it so far.
