Cannot read property 'ReactCurrentOwner' of undefined, js engine: hermes #313
Description
Environment
I have this in my package.json, but still RN one again can't do even a simple task without errors:
⚠️ react-native depends on @react-native-community/cli for cli commands. To fix update your package.json to include:
"devDependencies": {
"@react-native-community/cli": "latest",
}

Things I’ve done to figure out my issue
- [ X ] I used upgrade-helper to do my upgrade.
Upgrading version
0.77
Description
When upgrading from 0.75 to 0.77 I started getting this runtime error:
TypeError: Cannot read property 'ReactCurrentOwner' of undefined, js engine: hermes
TypeError: Cannot read property 'default' of undefined, js engine: hermes
TypeError: Cannot read property 'ReactCurrentOwner' of undefined, js engine: hermes
TypeError: Cannot read property 'default' of undefined, js engine: hermes
With new arch enabled I got this error:

Really hate this when every single time when I update RN the build breaks completely. Even when following the upgrade helper instructions. I really don't understand what the RN developers are doing when they can't keep comptability. Probably millions of developers just waste enormous amount of time just to fight with RN. Let's hope someone releases a better alternative than this total hack of a library.
