  1. Went ahead and upgraded all packages to latest releases in my environment and noticed this error. I reverted sentry-native version 0.63.0 -> 0.62.2 and this error popped up for a different package. I treated that package the same way and to my surprise yet another package complained about this error. This trend continued..

    reverted @sentry/react-native: node_modules/@invertase/react-native-apple-authentication/lib/version.js: [BABEL] /Users/admin/Documents/Repositories/react-native-app/node_modules/@invertase/react-native-apple-authentication/lib/version.js: Unknown option: .name.

    All in all after my goose chase I was able to pin point this entire issue to react-native-dotenv, I reverted 2.2.0 to 0.2.0. Everything else works fine with latest releases at the moment.

    TL:DR
    This solution might not be universal but I only had to reverse react-native-dotenv from 2.2.0 to: 0.2.0 to solve it.
