Issue present from: 4.4-dev 3
Issue Present up to: 4.6-dev 2 (latest experimental build)

System information

Godot v4.5.1.stable (f62fdbd) - Freedesktop SDK 25.08 (Flatpak runtime) on Wayland - X11 display driver, Multi-window, 2 monitors - Vulkan (Forward+) - dedicated AMD Radeon RX 7900 XT (RADV NAVI31) - AMD Ryzen 7 5700X 8-Core Processor (16 threads) - 31.22 GiB memory

Issue description

In my project file, no other scene other than this one crashes.
Normally i expect to load a scene and be able to use it without an issue, on this occasion the particular scene (note_splash.tscn) crashes moments after launching the scene.
So I decided to check the logs while running the editor through the terminal, and this error occurred.

handle_crash: Program crashed with signal 11
Engine version: Godot Engine v4.5.1.stable.flathub (f62fdbde15035c5576dad93e586201f4d41ef0cb)

Managed to reproduce this on windows 11 with the latest dev build (0fdbf05). It seems to get a read access violation in SceneTreeEditor::_get_node_configuration_warnings.

I guess the reason of crash is queue_free while on_ready. We can prevent crash by determining is_editor_hint()

	if !Engine.is_editor_hint():
		animation_finished.connect(queue_free)
