I had the same problem using expo build. I had to run expo buid:ios -c to reset all the credentials and it worked for me. The IPA size increased from around 40mb to 260mb.

Its taken me ages to sort this: The main thing I was missing as npm install expo-modules-core npm install expo-contants Think its pretty poor the way the eas upgrade works if Im honest. The original expo build worked well. I have also done a shed load of other dependencies so the above on its own may not help you so please upvote if it does so that others know.
