NPE in org.gradle.api.internal.plugins.DefaultPluginRegistry$RegistryAwarePluginImplementation.isAlsoKnownAs

Current Behavior

Gradle version: 8.6

This is a stacktrace in one of the flaky integration tests in Android Studio. It seems to point to an issue in Gradle build tool. The test opens a project in the IDE, which triggers Gradle sync. Sync fails with:
