Well the error is well explained

'Unable to convert instance of type 'Google.Android.Material.TextView.MaterialTextView' to type 'AndroidX.AppCompat.Widget.Toolbar'.'

You are trying cast an object with a different object. Simply, think like this

you are trying to cast a car into a carpet

So, it's not possible. That's why the error occured.
