Component used: KMP + Multiplatform Compose + Android Application Gradle Plugin + Room + KSP Version used: 2.7.0-alpha06

Initially issue was reported to Kotlin Team: https://youtrack.jetbrains.com/issue/KT-70966/Cannot-change-attributes-of-configuration-composeAppdebugFrameworkIosX64-after-it-has-been-locked-for-mutation

Where I've made the investigation and found multiple problems, including room gradle plugin. I found that Room Gradle Plugin has this code:

        project.tasks.withType(JavaCompile::class.java) { task ->
            if (androidVariantsTaskNames.isJavaCompile(task.name)) {
                val argProvider = configureBlock.invoke(task)
                task.options.compilerArgumentProviders.add(argProvider)
            }
        }

Calling tasks.withType(X::class.java) {} resolved into DomainObjectCollection.html#withType which is equal to tasks.withType(X::class.java).all {}. It is eager subscription API that will cause all tasks of type X to be resolved as soon as they're registered.

The correct API would be: tasks.withType(X::class.java).configureEach {}

See my report in the comments of KT issue for more details. Reproducer also attached.
