Well, I think the issue it’s indeed with some flipper dependency, but I have none!
According with this RN issue and this flipper issue it seems that I need to bump the flipper version as stated in this comment :
android/gradle.properties
FLIPPER_VERSION=0.144.0
How can I do that on expo for my dev build?
Edit1: Seems to be a mention to flipper in the Run gradlew expo build step:
> Task :react-native-webview:javaPreCompileDebug
> Task :react-native-webview:compileDebugJavaWithJavac
> Task :react-native-webview:bundleLibCompileToJarDebug

Edit2: Tested wit AVD devices with API 29, 30 and 31 and the result is the same, app crashes. I’m starting to think that maybe the issue is some change in Expo SDK 46 that triggers some Flipper usage in development builds, maybe the flipper version bump workaround should help, but I don’t know how to tell expo to do that.
