I am trying to run testcase using mockk and junit 5. Whenever I am trying to run the testcases I am getting this error, "java.lang.IllegalStateException: Could not self-attach to current VM using external process".

I am using JDK 17 and IntelliJ IDEA 2022.2.3 (Community Edition). bytebuddy versions:-

mockk:1.13.2

I was expecting that the testcases run without any exceptions or error.
