### Godot version

4.1 24cb43a

### System information

Windows 10 x64

### Issue description

Every time I launch Godot, I'm greeted with this in my console:
```
ERROR: Resource file not found: res://InputEventKey_7cuxk.
   at: (core\io\resource_loader.cpp:227)
```
Seems to be only happening in Project Manager and comes from this:
![](https://chat.godotengine.org/file-upload/udqZP8NQfogp4rjRL/Clipboard%20-%2021%20kwietnia%202023%2022:24)
It's part of my `editor_settings-4.tres`. I didn't test, but I think it applies to any shortcut that you customize. For some reason ResourceLoader tries to load it as a project resource, while it's a sub-resource.

Does not happen in 4.0.2.

### Steps to reproduce

1. Open Godot 4.1 project manager
2. Check the console
