System information

Godot v4.6.dev4 - Windows 11 (build 26200) - Multi-window, 1 monitor - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 2070 SUPER (NVIDIA; 32.0.15.8157) - AMD Ryzen 7 3800X 8-Core Processor (16 threads) - 31.92 GiB memory

Issue description

Console:
ERROR: Something attempted to free the root Node of a scene ("Main"). This is not supported inside the editor, so the Node was not freed.

Steps to reproduce

Create 2 scenes. Make one scene the child of the other scene.

While the "Main" scene is open, move the child scenes' file into another folder.
Above mentioned error shows and the "Main" scenes name changes from "Main" to "Main2". Renaming the scene back to "Main" does not work.

Moving the child scenes' file back or somewhere else changes the "Main2" scene name to "Main3" and so on.

Minimal reproduction project (MRP)

This is a check introduced in:

• Fix crash on queue free scene node in editor #112401

To fix:

• Editor hard crashes upon loading a scene with a node using queue free #112171

This shouldn't be happening here I'd say, this seems to be some weird edge case that might have crashed before and now was exposed
