Monad GHC.Prim.Any1 gets derived in a context
Because Monad GHC.Prim.Any1 gets derived in the type of the function test in the attached file, I cannot write an instance for it (obviously) and I cannot continue writing the code where I use the test function. I.e. I have this problem in a real project and it's blocking progress, until I find a work-around (which I didn't find after about an hour). I hope this gets fixed soon.
