I wonder if you know this issue. When I used firebaseConfig and firebaseAnalytics together and made the IPA. It crashes with this log.

Here is the project that has firebaseConfig and firebaseAnalytics entries in build.settings. I did not add the plist or json file. You can try your own.
Please have a look. Thanks.
