I'm seeing this error in the Metro terminal immediately after my Android build finishes loading:
TypeError: Cannot read property 'getConfig' of null
js engine: hermes
There is no stack trace — this is the entire error.
The issue began right after I removed react-native-reanimated from my project.
This only happens on Android.
The same code runs successfully on iOS (Xcode).
Clearing caches did not help: Watchman, Metro, node_modules, Gradle, and Android build folders were all cleaned.
I also tried adjusting build files and testing different libraries and Gradle plugin versions.
React Native: 0.75.2
Hermes: enabled
Android Studio: latest
Node: 18+

What could cause Android to throw getConfig of null when iOS builds fine, especially after removing Reanimated?
Is this a known issue with React Native 0.75.x and the Gradle plugin?
