### Godot version

4.0 beta 12 mono

### System information

MacOS 13.1, Apple M1 Pro

### Issue description

When `text_editor/external/use_external_editor` is set to true but `text_editor/external/exec_path` is not set and I create a new script and attach it to a node Godot freezes and i need to force quit the application.
Also after a restart when double clicking on the script the application freezes but I can quit normally

### Steps to reproduce

- Set Use External Editor to true in Editor Settings and leave Exec Path empty
- Create a new project with Moblie Renderer and Git Versioning in Godot
- Create a 3D Scene
- Create a gd script in the FileSystem inspector or directly attach the script to a node
