App crashes on throwing the exception from the Interceptor

There are the implementations i have been using

implementation 'com.squareup.retrofit2:retrofit:2.6.0'
implementation 'com.google.code.gson:gson:2.8.5'
implementation 'com.squareup.retrofit2:converter-gson:2.6.0'
implementation 'com.squareup.okhttp3:okhttp:4.2.1'
implementation 'com.squareup.okhttp3:logging-interceptor:3.10.0'

This is the network interceptor class

class NetworkConnectionInterceptor(
    context: Context
) : Interceptor {


    private val applicationContext = context.applicationContext

    override fun intercept(chain: Interceptor.Chain): Response {
        return if (!isConnectionOn()) {
            throw NoConnectivityException()
        } else if(!isInternetAvailable()) {
            throw NoInternetException()
        } else {
            chain.proceed(chain.request())
        }
    }

    private fun isInternetAvailable(): Boolean {
        return try {
            val timeoutMs = 1500
            val sock = Socket()
            val sockaddr = InetSocketAddress("8.8.8.8", 53)

            sock.connect(sockaddr, timeoutMs)
            sock.close()

            true
        } catch (e: IOException) {
            false
        }
    }

    private fun isConnectionOn(): Boolean {
        val connectivityManager =
            applicationContext.getSystemService(Context.CONNECTIVITY_SERVICE) as
                    ConnectivityManager

        return if (android.os.Build.VERSION.SDK_INT >=
            android.os.Build.VERSION_CODES.M) {
            postAndroidMInternetCheck(connectivityManager)
        } else {
            preAndroidMInternetCheck(connectivityManager)
        }
    }

    @RequiresApi(Build.VERSION_CODES.M)
    private fun postAndroidMInternetCheck(
        connectivityManager: ConnectivityManager): Boolean {
        val network = connectivityManager.activeNetwork
        val connection =
            connectivityManager.getNetworkCapabilities(network)

        return connection != null && (
                connection.hasTransport(NetworkCapabilities.TRANSPORT_WIFI) ||
                        connection.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR))
    }

    private fun preAndroidMInternetCheck(
        connectivityManager: ConnectivityManager): Boolean {
        val activeNetwork = connectivityManager.activeNetworkInfo
        if (activeNetwork != null) {
            @Suppress("DEPRECATION")
            return (activeNetwork.type == ConnectivityManager.TYPE_WIFI ||
                    activeNetwork.type == ConnectivityManager.TYPE_MOBILE)
        }
        return false
    }

}

My Retrofit client

operator fun invoke(
            networkConnectionInterceptor: NetworkConnectionInterceptor
        ): ApiUtil {

            val builder = OkHttpClient.Builder()
            builder.connectTimeout(5, TimeUnit.SECONDS)
            builder.writeTimeout(10, TimeUnit.SECONDS)

            val interceptor = HttpLoggingInterceptor()
            interceptor.level = HttpLoggingInterceptor.Level.BODY

            val client = OkHttpClient.Builder()
                .addInterceptor(interceptor)
                .addInterceptor(networkConnectionInterceptor)
                .build()


            builder.cache(null)

            val gson = GsonBuilder()
                .setLenient()
                .create()

            val retrofit = Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(GsonConverterFactory.create(gson))
                .client(client)
                .build()

            return retrofit.create(ApiUtil::class.java)
            
        }

this is how i am calling the api’s

fun onGetNationalities() {
        try {
            responseCallback?.onStarted()
            Coroutines.main {
                val nationalitiesResponse = repository.getNationalities()
                nationalitiesResponse?.let {
                    if (it.success) {
                        responseCallback?.onSuccess(it)
                    } else {
                        responseCallback?.onFailure(it.errorMessage)
                    }
                }
            }
        } catch (e: Exception) {
            responseCallback?.onAlert(
                e.cause?.localizedMessage
                    ?: MessageUtils.SOMETHING_WENT_WRONG
            )
        } catch (e: NoInternetException) {
            responseCallback?.onAlert(e.message!!)
        }catch (e: NoConnectivityException) {
            responseCallback?.onAlert(e.message!!)
        }
    }

NoInternetException and NoConnectivityException are two exception classes

class NoConnectivityException : IOException() {
    override val message: String
        get() =
            "No network available, please check your WiFi or Data connection"
}

class NoInternetException() : IOException() {
    override val message: String
        get() =
            "No internet available, please check your connected WIFi or Data"
}

This is not happening everytime for example if i am calling an api on button click and internet is not active, exception thrown from the intercepor will be caught in the function from where i am calling the api but if i call an api on the start on e.g signup form so i can get the nationalities for signup as in my example the interceptor will crash while throwing the exception plus it also crash sometime on the chain.proceed with the Sockettimeoutexception etc. The crash is reproducible.

If you throw an unchecked exception in an interceptor, OkHttp will report that to the uncaught exception handler. You can throw IOException instead if you want to catch it.

I have tried with these too but still crashing
