Yeah, we're late to the party and still using the old build system. Although when trying to use the new one, the same error still happens and it doesn't build.

On this repository, the project builds and works correctly! But I guess this happens since we don't really use these dependencies here (they were just installed via
post_install do |installer|
installer.pods_project.targets.each do |target|
if %w(RNScreens RNCMaskedView react-native-safe-area-context).include?(target.name)
target.remove_from_project

end
