### Godot version

4.2 eb4301b

### System information

Windows 10.0.19045 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1060 (NVIDIA; 30.0.15.1403) - Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz (8 Threads)

### Issue description

Sometimes when trying to open a scene from filesystem dock, the editor will crash. It happened 3 times to me already, but I don't know what exactly causes it.

### Steps to reproduce

1. Open a project
2. Open a scene

I think the scene needs to be opened early enough.
