when I updated to both Kotlin 1.6.21 and 1.6.20 I got this error

What is the version of compose you're using? You can't just upgrade to a later version of Kotlin.

I use compose 1.2.0-alpha01-dev620

this version is not compatible with kotlin 1.6.20

See discussion in https://kotlinlang.slack.com/archives/C01F2HV7868/p1650558671890619?thread_ts=1650558671.890619&cid=C01F2HV7868

Looks like `0.0.0-master-dev673`was not found So the official compose jb is not yet compatible for kotlin 1.6.21/20, yet ?

Snapshots build are only published on JetBrains Space snapshot repo, not on mavenCentral.

Thank you It works for Android / Web but I got this weird error for Desktop
