Just installed the plugin (IDEA 2022.2.3, ideaGinkgo 0.6.5). Got a bunch of exceptions.

class com.github.idea.ginkgo.GinkgoRunConfiguration cannot be cast to class com.github.idea.ginkgo.GinkgoRunConfiguration well thats a weird thing to say

Indeed :) It sounds like a "class loaded multiple times by different class loaders" problem; they have the same name but they're incompatible. When I installed the plugin IDEA went a little bonkers for a moment before coming to its senses. I had many projects open at the time (maybe 15?), many of them Go (but not all).
