Describe the bug Step execution

5. It is impossible to move to the next fragment on Kotlin 1.4.20

To Reproduce From kotlin 1.4.20 synthetic view has been removed. You can use findViewById or ViewBinding instead https://developer.android.com/topic/libraries/view-binding/migration

Expected behavior Uses up-to-date documentation and valid technologies, up-to-date language versions

Screenshots Uses outdated constructs, non-current versions of the language

Codelab details (please complete the following information about the codelab):
