Simple web server causing Exception 0xc0000005 windows 10


I'm a student brand new to golang and I'm trying to make a simple web app to learn. For reasons I don't understand if I write any program other than a simple "hello world" I get an Exception 0xc0000005. I've tried rebooting my machine and the error still persists. I think it's some sort of deadlock/POSIX issue?

If it matters, I'm using Windows 10.

Can anyone explain why this keeps happening? Is it something with the code?

Another user had a similar issue here but I don't see how it was resolved.

Thanks in advance.

Simple web app code in main.go:

import (

func handlerFunc(w http.ResponseWriter, r *http.Request){
    fmt.Fprint(w, "<h1>Welcome to my website</h1>")

func main() {
    http.HandleFunc("/", handlerFunc)
    http.ListenAndServe(":8000", nil)
