I was having the same issue, I have created a backup folder called node_modules_backup as a backup since I has going to remove the node_modules to install all the modules again, after I removed the node_modules_backup folder, the problem stoped and everything starts to run fine.

for those who use AWS Amplify and having duplicated file error from jest-haste-map you can ignore the package.json file inside the #current-cloud-backend folder by adding below code inside metro.config.js file:

module.exports = {
  resolver: {
  blacklistRE: /#current-cloud-backend/
  }
};
