I face this issue and I do not have any clue about what is cause the problem.
It’s about a React Native App, I didn’t install anything from days or change code. It’s happen from the moment I update my macOS Ventura to Sonoma.

I tried clean the cache of Node, delete the node_module and package-lock then reinstall everything.
I tried the same with Cocoapods.
I looked on Google.
Nothing help me to found a way.
And now StackOverflow continu to ask me to add some details because I have to much code on my text… Thanks to make me life bad. So I delete some package from the list, sorry.
Thanks for your help.

Thanks for your answer @Pratik.
I wasn't sure what you want to point first, but after a while, reading and looking your links I found one solution works for me here : https://github.com/facebook/react-native/issues/29605#issuecomment-861783673
Now, because I can install all Pods I need, I run this command :
npm run iosBut one "original" error show up (original because it was my first problem before I'am trying to found a solution on Google - which give me the error I show first on this page).
Here it's what I get on Terminal (I cut some lines because I have 1600 lines)
Thanks
The native module for Flipper seems unavailable. Please verify that react-native-flipper is installed : https://github.com/facebook/flipper/issues/1253

It seems like you are encountering an issue while installing the hermes-engine during the CocoaPods installation process for your React Native project.
Manually installing the hermes-engine by downloading the source code from the GitHub repository (https://github.com/facebook/hermes/releases) and adding it to your project
