Channel is not recieving data or giving dead block

Getting Help Code Review
1

I’ve the below code:

//main.go
package main

import (
	"edriven/events"
	"fmt"
	"math"
	"time"
)

func main() {
	fmt.Println("Starting")
	events.Wg.Add(1)
	go events.User.Trigger("new", "Hasan")
	events.Wg.Add(1)
	go events.User.Trigger("name", []any{"Hasan", "Ali"})
	events.Wg.Add(1)
	go events.User.Trigger("new", "Ali")

	//for x := range <-events.Publish {
	//	fmt.Println(x)
	//}

	for {
		select {
		case x := <-events.Publish:
			fmt.Println(x)
		default:
			fmt.Println("waiting for data ...")
			time.Sleep((time.Duration(math.MaxInt64)))
		}
	}
}

And

//events/user.go
package events

import "fmt"

var User Events

func init() {
	User.register("new", func(payload ...any) {
		fmt.Println(payload[0])
		//message := make(map[string]string)
		//message["new"] = "done new"
		Publish <- "{'new':'done'}"
		Wg.Done()

	})

	User.register("name", func(payload ...any) {
		for index, person := range payload {
			fmt.Println(person, index)
		}
		//message := make(map[string]string)
		//message["name"] = "done name"
		Publish <- "{'name':'done'}" //message
		Wg.Done()
	})
}

And

//events/setup.go
package events

import "sync"

var Wg sync.WaitGroup
var Publish chan string

/*var Publish chan map[string]string

func init() {
	Publish = make(chan map[string]string)
}
*/
type Event struct {
	Name   string
	Action func(...any) // <-chan string // func(...any) ([]any, error)

}

type Events struct {
	handlers []Event
}

func (e *Events) register(name string, action func(...any)) {
	e.handlers = append(e.handlers, Event{
		Name:   name,
		Action: action,
	})
}

func (e *Events) Trigger(name string, payload ...any) {
	for _, event := range e.handlers {
		if event.Name == name {
			event.Action(payload)
		}
	}
}

The output I got is as below, that is nothing is exchanged through the channels

If I replaced the for { select {} } loop by the for x := range <-events.Publish { } loop then I get the below error:
