### Godot version

4.2.rc2 (1ba920fada9efc8c4476ded50fe673b8db541366)

### System information

Mageia 9 - Vulkan (Forward+) - dedicated AMD Radeon RX Vega M GL Graphics (RADV VEGAM) () - Intel(R) Core(TM) i7-8705G CPU @ 3.10GHz (8 Threads)

### Issue description

Passing `--rendering-method forward_plus` on the command line to a project configured with `gl_compatibility` as rendering method leads to a crash:
```
ERROR: Cannot instantiate RenderingDevice-based renderer with renderer type gl_compatibility
   at: RendererCompositorRD (./servers/rendering/renderer_rd/renderer_compositor_rd.cpp:321)
ERROR: Parameter "scene" is null.

```

This also seems reproducible in 4.1.3.

Likewise, passing `--rendering-driver vulkan`, or both (`rendering-method forward_plus --rendering-driver vulkan`) crashes similarly.

The issue also happens with `--rendering-method mobile`.

On the other hand, passing `--rendering-method gl_compatibility` and/or `--rendering-driver opengl3` to a RD-based project (`forward_plus` or `mobile`) works fine.

### Steps to reproduce

- Create new GL Compatibility project
- Run it from command line with `--rendering-method forward_plus`

### Minimal reproduction project

Happens in a brand new GL Compatibility project.
