I have the following code:

arguments?.getString(FORCED_EMAIL).let {
      binding.etEmail.setText(it)
      binding.etEmail.isFocusable = false
      binding.etEmail.isEnabled = false
    }

getString() returns null. Anyone has an idea why this goes through and executes statements inside let?

let just scopes the receiver which in this case is nullable. So your it will still be nullable. If you want to avoid calling the lambda for null, use ?.let
