You are declaring consentInformation as a nullable field in line 14:

private var consentInformation: ConsentInformation? = null

As the field is mutable, its value could have changed between the execution of line 23 and line 24, so the compiler disallows you to refer to it without a null check.

In this specific case you could just change the field to be lateinit as you're assigning it in the onCreate method, which is executed first.

private lateinit var consentInformation: ConsentInformation
