Additional Context

Problem started happening after upgrading React Native from 0.72.4 to 0.73.1.

[wkirby]

Reverting my project back to an earlier commit, where we are running React Native 0.72.4 works as expected. Something appears to have changed between 0.72 and 0.73 which causes this issue.

[wkirby]

I went back and walked through each patch update form 0.72.4 to 0.73.1, changing nothing else about the project, and the problem does not appear. I'm currently working through updates on other packages 1 at a time to establish what causes this error to start happening.

I am doing so on 0.72.7, as 0.73.1 has some incompatibilities with other libraries in use by our app.

[wkirby]

Ok, on RN 0.72.7 with react-native-iap 12.10.8 everything is working, react-native-iap 12.12.1 throws the above EXC_BAD_ACCESS error

I also get bad_access crashes a lot on ios

Coming back to this, as we now need to update the IAP library for android. I've tracked the problem to this PR: https://github.com/dooboolab-community/react-native-iap/pull/2518

Version 12.10.8 works just fine, 12.11.0 is broken before the application finishes launching. I am not a Swift expert by any stretch, but I suspect that there's something about our XCode project and the storekit configuration.

@arthurgeron any chance you have insight on this?

[wkirby]

I have stripped out my entire storekit configuration, and removed every piece of javascript related to react-native-iap and I am still encountering this error, just by virtue of having the react-native-iap pod installed in our project.

I took some time to delve into the EXC_BAD_ACCESS error in Swift, and it appears to be something related to concurrency. My new guess, since this library appears to work for other people, is that there is something about the configuration of our application that is causing the issue, but I'm at a total loss on how to continue debugging.
