Not sure if it's the same thing but for me my solution was an issue with the packages, they had s.dependancy as React when it should be React-Core. See here: https://github.com/facebook/react-native/issues/29633#issuecomment-694187116

You can manually change them to see if it works for you and then use the patcher as suggested to fix the libraries.
