UPDATE: there was a library trying to use React Native 64 or newer, and the EventDispatcher.java file changed a lot from 63.5 to 64+. That was the cause of expecting an Interface while i was running a class file.
Last week a project I have was building correctly, then an error started appearing out of nowhere when running it. It was a problem with the library invertase/react-native-apple-authentication about using Kotlin 1.6.0 in the metadata but was expecting Kotlin 1.4.0.
After forcing the project to use Kotlin 1.6.0 with kotlinVersion = "1.6.0" in build.gradle, now this error started appearing, after building successfully, the app crashes without warning, just closes completely, and this error appeared in the Logcat:
java.lang.IncompatibleClassChangeError: Found class com.facebook.react.uimanager.events.EventDispatcher, but interface was expected (declaration of 'com.facebook.react.uimanager.events.EventDispatcher' appears in /data/app/APP_NAME_ROUTE==/base.apk)

Im not a native Java expert an im having trouble finding out how to fix this issue, if someone has a hint of at least how to approach, would be awesome.
React Native 62.3 React 16.11.0 react-native-reanimated: 1.13.2
Tried updating the invertase/react-native-apple-authentication library, the kotlin version, updating the react-native-reanimated library to 2.x but its a complete mess since I have more libraries that still use 1.x version.
Already tried upgrading the React Native version to the newest I could, but due to the nature of the proyect, some important libraries in the core of the project are very old and won´t work with the newer versions, if I can´t solve this issue for now, I will need to make a new project from scratch.
Solution: there was a library trying to use React Native 64 or newer, and the EventDispatcher.java file changed a lot from 63.5 to 64+. That was the cause of expecting an Interface while I was running a class file.
