What causes the Unresolved reference: WebViewClient error?

Question

Android

Good afternoon!
MainActivity.kt

package com.example.test

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import kotlinx.android.synthetic.main.activity_main.*

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        webViewSetup()
    }
    private fun webViewSetup() {
        wb_WebView.webViewClient = WebViewClient()

        wb_WebView.apply {
            loadUrl("https://yandex.ru")
        }
    }
}

An error occurs:
