Kotlin app crashes when switching activity

Hello, i have a problem with switching activitys in my app. I made a button that switches the activitys but everytime i press the button my app crashes. Android studio also gave me a few error codes. I have these in a screenshot and also the code for the activity switch. Would be great if someone could help.

   override fun onCreate(savedInstanceState: Bundle?) {
        val MainActivity2 = findViewById<Button>(R.id.button)
        MainActivity2.setOnClickListener {
            val Intent = Intent(this,MainActivity2::class.java)
