How To Reproduce
Set an action to point to a virtual void. For example:

using System;
using Sys = Cosmos.System;

namespace CosmosKernel15
{
    public class Kernel : Sys.Kernel
    {
        protected override void BeforeRun()
        {
            Action action = Test;
        }

        protected override void Run() { }

        public bool a;

        public virtual void Test()
            => a = true;
    }
}
