Thanks for the report!

This looks like a bug in Godot - there's this code in CollisionObject3D:

void CollisionObject3D::_mouse_enter() {
	if (get_script_instance()) {
		get_script_instance()->call(SceneStringNames::get_singleton()->_mouse_enter);
	}
	emit_signal(SceneStringNames::get_singleton()->mouse_entered);
}

void CollisionObject3D::_mouse_exit() {
	if (get_script_instance()) {
		get_script_instance()->call(SceneStringNames::get_singleton()->_mouse_exit);
	}
	emit_signal(SceneStringNames::get_singleton()->mouse_exited);
}

It should be using GDVIRTUAL_CALL() rather than checking if get_script_instance() is truthy. I'll make a PR to Godot.

I just posted PR godotengine/godot#85870 which should fix this!

As an interim fix (before the PR is merged), you could connect to the mouse_entered and mouse_exited signals, rather than overriding the virtual methods

Hello, I wanted to try the new GDExtension hot reloading and was playing arround with it when I got stuck with trying to have Area2D react to mouse events from GDExtension. I thought I was doing somehting wrong but turns out that was a genuine bug, and it is exactly the same error as here except for a slightly different case.
I already fixed it and made a PR godotengine/godot#86908
Its essentially exactly the same fix, except for it also has the functions _mouse_shape_enter and _mouse_shape_exit which have the exact same behavior.

Maybe this issue should be generalized to cover both cases since they are so similar?
