Have been using SDK version 3.5 for the past 2 weeks, but suddenly stopped working. So tried to use SDK version 4.0.0, but same error.

**Please provide the Web3Auth initialization and login code snippet below:**

```auto
import EncryptedStorage from 'react-native-encrypted-storage';
// const redirectUrl = https://dev-sdk.openlogin.com ;
// const redirectUrl = ariseweb3auth://auth;
const redirectUrl = ariseweb3auth://openlogin;
const clientId = WEB3_AUTH_CLIENT_ID;
const web3AuthParams: SdkInitParams = {
clientId,
network: OPENLOGIN_NETWORK.TESTNET,
loginConfig: {
// Add login configs corresponding to the provider
// For firebase/ cognito & other providers, you need to pass the JWT token
// JWT login
jwt: {
verifier: ‘arise-auth-verifier-testnet’, // Please create a verifier on the developer dashboard and pass the name here
typeOfLogin: ‘jwt’,
clientId
}
// Add other login providers here
}
};
const web3auth = new Web3Auth(WebBrowser, EncryptedStorage, web3AuthParams);
const login = async (loginProvider: string) => {
return new Promise(async (resolve, reject) => {
try {
const response = await web3auth.login({
loginProvider,
redirectUrl,
mfaLevel: MFA_LEVELS.OPTIONAL,
curve: ‘secp256k1’
});
  resolve(response);
} catch (err) {
  reject(err);
}

@kevin.janada Plug and Play doesn’t support Sapphire Devnet yet.  
Pls deploy on mainnet/cyan/aqua directly and use it
