We see this failure on Kotlin 1.6-M1, worth filing or known?

Caused by: java.lang.NoSuchMethodError: 'org.gradle.api.provider.Property com.google.devtools.ksp.gradle.KspTaskJvm.getUseClasspathSnapshot()'

It should be fixed in KSP main already. KSP main branch is currently targeting some early snapshot version of Kotlin 1.6.0, although not quite 1.6.0-M1. We keep updating to Kotlin master every few weeks.
