kotest: `java.lang.NoClassDefFoundError`: Individual tests/categories in spec do not load required classes

Kotest 5.6.2

Here’s a simple example of a test spec:

>> class SimpleTest : DescribeSpec({
>    describe("Category") {
>        it("Test") {
            0 shouldBeEqual 0
        }

>        it("Test 2") {
            Origin.SERVER shouldNotBeEqual Origin.CLIENT
        }
    }
})

In Android Studio (I assume IntelliJ as well, but I haven’t tried), the > and >> represent icons on the left sidebar that I can click to run tests. Clicking on the >> for a full spec works every time. In the example, clicking the > next to “Test” would work too. However, I get an error when I click the icon next to “Test 2”:
