Same issue on react-native

Removing this snippet fixed it for me:

              var core = function () {
                try {
                  return require("core-js/modules/_core");
                } catch (e) {
                  // Older versions of core-js had a different file layout.
                  return require("core-js/modules/$.core");
                }
              }();
