Library not working with Expo SDK 54

Hello. We have been constantly trying to work around this by using everything listed on here, but it is not working for some reason.
The app was initially built in Expo SDK 54 and has since been ejected. We have tried keeping the imports of RNCallkeep in swift file and that didn't work, as has been the case with everyone - "RNCallKeep not found" error. Also tried listing it in the Bridging-Header file and that's when these two errors arose-

1.) Failed to emit precompiled header '/Users/mc559/Library/Developer/Xcode/DerivedData/[AppName]-gthpjwqbmzgdepbcdzmuhlqwpyuk/Build/Intermediates.noindex/PrecompiledHeaders/[AppName]-Bridging-Header-swift_1LS8Z4CYI0BYD-clang_1MEDN0KIR5C77.pch' for bridging header '/Users/mc559/Desktop/[AppName]/ios/[AppName]/[AppName]-Bridging-Header.h'

2.) RNCallKeep - RNCallKeep.h:15:9 'React/RCTEventEmitter.h' file not found

Here is the package.json:

Start with AppDelegate.swift, the [AppName]-Bridging-Header.h file, and RNCallKeep.h, then reproduce the iOS build using the Expo SDK 54 project and its expo run:ios script. Done means RNCallKeep is found and the bridging-header errors, including the missing React/RCTEventEmitter.h file, no longer occur.
