after upgrading to xcode 12.0 getting 'folly/json_pointer.h' file not found

Description

After upgrading to Xcode 12.0 I am no longer able to build my project and am getting 'folly/json_pointer.h' file not found.

I've also tried building a completely new project to compare, however the new project also gets the same issue

To reproduce:

npx react-native init AwesomeProject
cd AwesomeProject
npx react-native run-ios

I am also getting the same 'folly/json_pointer.h' file not found
fatal error: 'folly/CppAttributes.h' file not found
fatal error: 'folly/Unicode.h' file not found
fatal error: 'folly/concurrency/UnboundedQueue.h' file not found

React Native version: 0.63.2

mac OS 10.15.4
xcode 12.0

I downgraded back to xcode 11.7 and had to try and clean everything and was able to get my build working again:

cd ./guest-app/ios && npx rimraf Pods && pod cache clean --all && npx rimraf build
watchman watch-del-all
yarn cache clean
npx rimraf ~/Library/Developer/Xcode/DerivedData && npx rimraf $TMPDIR/metro-* && npx rimraf $TMPDIR/react-* && npx rimraf $TMPDIR/haste-*
cd ./guest-app && npx rimraf node_modules 

not sure if I had tried the above if I could have got xcode 12.0 to work with my build

I have the same issue after upgrading to react native 0.71.1, this is my Podfile

# If you are using a `react-native-flipper` your iOS build will fail when `NO_FLIPPER=1` is set.
# because `react-native-flipper` depends on (FlipperKit,...) that will be excluded
#
# To fix this you can also exclude `react-native-flipper` using a `react-native.config.js`
# ```js
# module.exports = {
#   dependencies: {
#     ...(process.env.NO_FLIPPER ? { 'react-native-flipper': { platforms: { ios: null } } } : {}),
