Godot version
4.0.2 stable
System information
macOS Monterey (12.6.2), Apple Blackmagic eGPU (Radeon Pro 580)
Issue description
Attempting to launch Godot Editor app directly with "Prefer External GPU" will cause it to render blank background at launch.

I have waited for more than 10 minutes and it doesn't seem to do anything.
Launching Godot by clicking project file, however, doesn't seem to suffer from the same problem, here is me testing the Lumberyard Bistro scene ported to Godot.

Steps to reproduce
- Set "Prefer External GPU" option in Godot app's Info menu.
- Test opening Godot app directly vs opening Godot via project file.
Note in the first case, Godot doesn't hang, nor does it output any relevant errors to macOS Console;
In the second case Godot launch correctly, outputs some Metal compilation error but doesn't prevent normal usage.
Also note that Blackmagic is an Apple certified eGPU device with native macOS support, so no third-party driver were installed.
