Issue description

Hi, sorry fo my english.
I use ResourceLoader.LoadThreadedRequest to load some scene inherited from a scene with C# script, will print some error like this:

E 0:00:02:0048   Godot.NativeInterop.NativeFuncs.generated.cs:1535 @ void Godot.NativeInterop.NativeFuncs.godotsharp_pusherror(Godot.NativeInterop.godot_string& ): Cannot load script for type 'BaseScene'. Path: 'res://BaseScene.cs'.

Steps to reproduce

1. BaseScene.tscn with BaseScene.cs
2. ChildScene.tscn with ChildScene.cs, ChildScene.tscn inherited from BaseScene.tscn and ChildScene.cs inherited from BaseScene.cs
3. use ResourceLoader.LoadThreadedRequest to load ChildScene.tscn

Have you built your scripts?

yes, I built it

Can replicate here. Your demo project didn't seem to have the inherited scene/script mentioned, so I added those inherited from the BaseScene scene/script. Yes, I get the same error.

Edit: did note however that the scene seems to instantiate and execute the child script fine, despite the error about loading the parent script.

Setting useSubThreads to false in the threaded load parameters doesn't cause the error.

I think #74405 may fix this.

Edit: yes, Godot 4.1 beta 1 (which includes the above PR) doesn't error with useSubThreads set to true.

I test it in Godot 4.1 beta 1. Looks like there's no problem in first run, but the status by ResourceLoader.LoadThreadedGetStatus always in InProgress in rerun.
