Capacitor: Unable to load capacitor.config.json

Creating an Ionic 5 app with Capacitor, I'm running into this problem where it seems that capacitor.config.json is not being loaded.
This problem came after I've installed #codetrix-studio/capacitor-google-auth, before the project was running on android fine.
{
"appId": "com.luyou.clauncher",
"appName": "c-launchpad",
"bundledWebRuntime": false,
"npmClient": "npm",
"webDir": "www",
"plugins": {
"SplashScreen": {
"launchShowDuration": 0
},
"GoogleAuth": {
"scopes": [
"profile",
"email"
],
"serverClientId": "xxxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com", // On my project I'm using the real server client id
"forceCodeForRefreshToken": true
}
}
}
On the android studio the build goes okay but when you try to open the app, it does crash with the following:

capacitor.config.json is already on the root path of the project and doing npx cap copy or npx cap sync doesn't solve this problem, but actually is copying the www files. For some reason, the capacitor config simply is just not being copied.

Seems like Capacitor alpha versions are broken, so gonig back to Capacitor 2.4.7 fixes the problem. The capacitor.config.json is loading correctly and the native plugins are loading fine.

awesome, thanks #Adrian Legaspi.
Downgrading to capacitor 2.4.7 solved it for me.
This is what my package.json looks like:
"dependencies": {
...
"#capacitor/android": "^2.4.2",
"#capacitor/core": "2.4.7",
..
},
"devDependencies": {
...
"#capacitor/cli": "2.4.2",
...
}

DeepSpeechDemo App works with Gradle cli but crashes when built with Android Studio

The android-mic-streaming demo works off-the-shelf using ./gradlew installDebug, but when the play button in Android Studio is used to compile and install the exact same project it crashes with the following after tapping record:

The issue seems to be related to libdeepspeech-jni.so not being included when Android Studio is used. I am completely new to Android development (I'm building a Mozilla-STT React Native module and only supporting iOS is useless) so this is especially confusing.
Thanks!
EDIT:
Hours of random trial and error later: Changing this option from "Default APK" to "APK from app bundle" in Android Studio made the demo start working
However, doing the same on my example app for the React Native module (which has a dependency android project which finally depends on the actual libdeepspeech) didn't work. It started working when using x86_64, so there must be no libdeepspeech x86 binary.

Android app crash after NDK upgraded from 20.1 to 21.0

I was using Android Studio to create an app using Java, Kotlin and C++.
Yesterday, I upgraded the Android NDK from version 20.1 to version 21.0, and then the android studio keeps crash if I connect to my android phone and run.
The piece of crash log in Logcat is as below.

Thank you very much for your help!

That problem mentioned in ndk repo. They suggests to use flag -static-openmp.
I put the flag in my CMakeLists.txt like:
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fopenmp -static-openmp")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fopenmp -static-openmp")
and that's do the job.
