Starting an individual test fails with java.lang.NoClassDefFoundError: io/kotest/common/ConcurrentHashMapKt

[Spikhalskiy]

When trying to run an individual context or a should node of ShouldSpec Idea, I'm getting "Test framework quit unexpectedly" with

Exception in thread "main" java.lang.NoClassDefFoundError: io/kotest/common/ConcurrentHashMapKt
	at io.kotest.engine.listener.CollectingTestEngineListener.<init>(CollectingTestEngineListener.kt:11)
	at io.kotest.engine.launcher.MainKt.main(main.kt:25)
Caused by: java.lang.ClassNotFoundException: io.kotest.common.ConcurrentHashMapKt

	at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:525)
	... 2 more

Running the whole spec works fine.

The problem is present with both "Run tests using: Gradle (Default)" and "Run tests using: IntelliJ Idea"
