sourceSet.kotlin.nonSelfDeps(kspTaskName).filter { it.name !in filteredTasks }

This line is accessing task dependencies, which breaks Gradle Isolated Projects. This occurs when using AGP 9 with KSP 2.3.6. Repro project https://github.com/pablobaxter/starrynight

Steps:

• Change com.frybits.agp.version to 9.0.0 in the gradle.properties file
• Sync project

The following stacktrace is reported for this issue:

Looks like I was missing ksp.project.isolation.enabled=true as a property.
