Issue description

Godot editor crashes with error while recompiling library.

Steps to reproduce:

1. Сompile the code and run Godot (with gd command).

package main

import (
	"grow.graphics/gd"
	"grow.graphics/gd/gdextension"
)

type NewLabel struct {
	gd.Class[NewLabel, gd.Label]
}

func main() {
	godot, ok := gdextension.Link()
	if !ok {
		return
	}
	gd.Register[NewLabel](godot)
}

2. Add a new object "NewLabel" in the Godot editor via "Add Chid Node".

3. With the editor running, recompile the library.

gd build

or

go build -o ./graphics/windows_amd64.dll -buildmode=c-shared

Then Godot editor crashes with error:

I'm not sure how solvable this is, Go doesn't strictly support dlclose when compiled to a shared library, so you get these weird inconsistent issues when you reload the extension. In my case, it works sometimes, other times, Godot will crash.

Same here! But editor just closes silently. Without any additional logs
