Update from SDK 28 to 29 fails on deployment to iOS simulator

I have an app running successfully on the iOS simulator, SDK28 with all the appropriate versioning and configs.

After upgrading to 29, the app builds successfully in Xcode. Once it starts running on the simulator it fails with the following backtrace. This failure occurs before the javascipt is loaded - the same things happens whether or not the metro bundler is running. I am not currently using any custom native modules. I am having a hard time finding any information about this error online and could use some help debugging it.

Since this seems like an issue with the native code, here’s my podfile, which is a copy of this (provided in the upgrade guide) updated to reflect my project name, and some changes to node_modules paths and the case of some of the package names to resolve known issues.

I have walked through the upgrade multiple times all with the same error, tried upgrading to newer SDKs, updated node modules and pods, and done some research on what looks like the culprit, FrontBoardServices. The only reference to this I can find anywhere is in react-native-sentry (version 0.36.0), a dependency of sentry-expo (v 1.9.0). Although I doubt this is the culprit, I removed all reference to sentry in the app, including the package, rebuilt etc., same problem.

Not sure what to do for next steps, any help is very much appreciated!
