База данных sqLite Kotlin Android создаётся. Но данные в неё не добавляются

База данных создаётся но данные полученные с EditText(данные из Edit Text приходят корректно, проверял) не записываются в Базу данных.

Name Class:

import android.provider.BaseColumns

object CampDbNameClass : BaseColumns{

const val TABLE_NAME = "authorization"
const val COLUMN_NAME_LOGIN = "login"
const val COLUMN_NAME_PASSWORD = "password"
const val COLUMN_NAME_SQUAD = "squad"

const val DATABASE_VERSION = 1
const val DATABASE_NAME = "Camp.db"

const val CREATE_TABLE_AUTHORIZATION =
    "CREATE TABLE IF NOT EXISTS $TABLE_NAME (" +
            "${BaseColumns._ID}  INTEGER PRIMARY KEY AUTOINCREMENT ," +
            "$COLUMN_NAME_LOGIN  TEXT," +
            "$COLUMN_NAME_PASSWORD TEXT,"+
            "$COLUMN_NAME_SQUAD INTEGER)"

const val DELETE_TABLE = "DROP TABLE IF EXISTS $TABLE_NAME"

}

Activity из которого вызывается фрагмент, в котором происходит чтение и добавление в БД.

import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import androidx.viewpager.widget.ViewPager
import com.example.singupactivity.databinding.ActivityMainBinding
import com.google.android.material.tabs.TabLayout
import com.example.singupactivity.ui.main.Adapter.ViewPagerAdapter
import com.example.singupactivity.ui.main.DataBase.CampDbManager
import com.example.singupactivity.ui.main.Fragment.LoginFragment
import com.example.singupactivity.ui.main.Fragment.SignupFragment

class CampMainActivity : AppCompatActivity() {

private lateinit var binding: ActivityMainBinding
private val campDbManager = CampDbManager(this)

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    binding = ActivityMainBinding.inflate(layoutInflater)
    setContentView(binding.root)
    campDbManager.openDb()

    setUpTabs()
}

private fun setUpTabs() {
    val viewPager: ViewPager = binding.viewPager
    val tabs: TabLayout = binding.tabs
    val adapter = ViewPagerAdapter(supportFragmentManager)
    adapter.addFragment(LoginFragment(), "Login")
    adapter.addFragment(SignupFragment(), "Signup")
    viewPager.adapter = adapter
    tabs.setupWithViewPager(viewPager)

}

override fun onDestroy() {
    campDbManager.closeDb()
    super.onDestroy()

}
