Error Building For Windows

Compiling an app for windows amd64 gives me this error below, I tested this on both Linux (Fedora 40) & Windows 10 in a VM:

here's a simple test app that has the same error:

package main

import (
    "log"
    "os"

    "github.com/diamondburned/gotk4/pkg/gdk/v4"
    "github.com/diamondburned/gotk4/pkg/gio/v2"
    "github.com/diamondburned/gotk4/pkg/gtk/v4"
)

func main() {
    app := gtk.NewApplication("com.test.asdf", gio.ApplicationFlagsNone)
    app.ConnectActivate(func() { activate(app) })

    if code := app.Run(os.Args); code > 0 {
        log.Println("error code: %d", code)
    }
}

func activate(app *gtk.Application) {
    window := gtk.NewApplicationWindow(app)
    window.SetDefaultSize(800, 500)

    gtk.StyleContextAddProviderForDisplay(
        gdk.DisplayGetDefault(),
        loadCSS(""),
        gtk.STYLE_PROVIDER_PRIORITY_APPLICATION,
    )

    child := gtk.NewLabel("test")

    window.SetChild(child)
    window.SetVisible(true)
}

func loadCSS(content string) *gtk.CSSProvider {
    prov := gtk.NewCSSProvider()
    // ...
    return prov
}
