Error secure random number generation not supported by this browser use chrome, FireFox or Internet Explorer 1

Hi.
I use 'crypto.publicEncrypt' in my code RN. Android test, release and Ios test word good, but IOS release error 'Error secure random number generation not supported by this browser use chrome, FireFox or Internet Explorer 1'

System:
React-native-cli: 2.0.1
React-native: 0.61.5
Node: v12.11.1

My code:
RNRandomBytes.randomBytes(24, (err, bytes) => {
const randomAESkey = bytes
const sha256Pass = CryptoJS.HmacSHA256(password, Config.SHARE_KEY)
const key = CryptoJS.enc.Base64.parse(randomAESkey)
let iv = new Buffer(randomAESkey, 'base64').slice(0, 16).toString('base64')
iv = CryptoJS.enc.Base64.parse(iv)
const aes256Pass = CryptoJS.AES.encrypt(sha256Pass, key, { iv: iv, mode: CryptoJS.mode.CBC, })
const deviceId = DeviceInfo.getUniqueId()
const RSA_PKCS1_PADDING = 1
console.log('Buffer.from(randomAESkey) ', Buffer.from(randomAESkey))
const enc = crypto.publicEncrypt( --> Begin error
{
key: Config.APP_PUBLIC_KEY,
padding: RSA_PKCS1_PADDING,
},
Buffer.from(randomAESkey),
)
const data = {
Password: aes256Pass.toString(),
UserName: (registerOrLoginState && registerOrLoginState.Phone) || '',
IsProvideKey: true,
Imei: deviceId,
EncryptKey: enc.toString('base64'),
SessionId: '',
DeviceType: Platform.OS.toUpperCase(),
}
}
