Why IntelliJ Kotest plugin does not work well?

I've installed the Kotest plugin (1.1.22-IC-2020.3) for IntelliJ (2020.3). It allows me to create Kotest tests for/from my Kotlin classes, but those tests are not runnable from the test classes.

The kotest panel showing as if no test are present

If I create a new Kotest run configuration I can run the test class, but this exception is always thrown:

The test class compiles and the jar kotest-core-jvm-4.1.1.jar is included as external library.

Can someone give some advice on this?

According to the docs, you need 4.2 or higher and you're using 4.1.1. I would recommend you use 4.3.2.

To use the intellij plugin you need to add the kotest-framework-engine-jvm dependency to your build. If you are using the gradle support as well (eg for CI or running at the command line) and you have added kotest-runner-junit5-jvm then that will bring in the required dependencies transitively.
