I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Thanks for reaching out, @ACFancy. Could you provide a sample app that reproduces the issue?

[ACFancy]

@rizafran sample demo code

• run in Simulator
• click button many times for a shot time
• maybe crash

[rizafran]

Thanks for the sample app, @ACFancy. Unfortunately, I'm unable to open the app properly. Could you try to double-check the files?

[ACFancy]

@rizafran I run this project in XCode 14.0 beta.2, maybe have some changes with XCode 13.x

[ACFancy]

@rizafran

• I adjusted project format for compatiable for Xcode 12.0
• sample demo code

[rizafran]

Hi @ACFancy, I tried your sample app, but I was able to run it successfully without any error (though I only commented the post_install block from the Podfile since I'm getting a module not found error). Do you have any other error logs or additional stack traces to the ones you shared?

[ACFancy]

@rizafran

• I adjusted iOS deployment target to iOS 15.0, before that is iOS 16.0
• sample demo code
• I changed 10 requests to 10000 requests on one click button, the crash rate was up, one or two click may make crash
• you can try keep clicking button until crash happening;If not happened, can stop debug and retry debug, then try again
• without performance pod, the crash didn't happened.
• below is the crash stack snap image

We are experiencing the same issue on iOS Simulators and physical devices as well iOS 16.4, Firebase 9.4.1
