It turns out Firebase SDK problem. After updating to the latest Firebase SDK version 9.0, there is no crash on IOS. https://github.com/firebase/firebase-cpp-sdk/issues/700

Sorry for the late reply, I found that I can upload the archive to app store by opening Unity-iPhone.xcworkspace and manually uploading it, but fail by Jenkins. And I run xcrun altool --validate-app it shows error below I am not sure it's the reason why it fail to upload archive by using Jenkins.
