The latest version for Compose is 1.1.0-rc01 and supports Kotlin 1.6.0. Google released a specific compiler plugin version 1.1.0-rc02 to support Kotlin 1.6.10. The Workflow repository is using the two different versions, but they should be aligned once 1.1.0 goes stable.
Could you file an issue tracking this, and add a comment here?
